Solving equations is an essential skill in mathematics. It involves finding the value of the variable that makes the equation true. There are various methods for solving equations, including using inverse operations, substitution, and balancing both sides of the equation.

Equations can be classified into different types based on the operations involved. Some common types of equations include:

- Linear Equations: These are equations of the form ax + b = c, where x is the variable and a, b, and c are constants.
- Quadratic Equations: These are equations of the form ax^2 + bx + c = 0, where x is the variable and a, b, and c are constants.
- Exponential Equations: These are equations in which the variable appears in the exponent, such as 2^x = 16.

To solve a linear equation, we use inverse operations to isolate the variable on one side of the equation. The basic steps for solving a linear equation are:

- Use inverse operations to isolate the variable on one side of the equation.
- Perform the same operations on both sides of the equation to maintain equality.
- Simplify and solve for the variable.

Solve the equation 3x + 5 = 17.

We can solve this equation by following these steps:

Quadratic equations can be solved using various methods, such as factoring, completing the square, or using the quadratic formula. The basic steps for solving a quadratic equation are:

- Factor the quadratic equation, if possible.
- Use the quadratic formula: x = (-b ± √(b^2 - 4ac)) / (2a)
- Simplify and solve for the variable.

Solve the equation x^2 - 4x + 4 = 0.

We can solve this equation by using the quadratic formula:

x = (-(-4) ± √((-4)^2 - 4(1)(4))) / (2*1)

x = (4 ± √(16 - 16)) / 2

x = (4 ± 0) / 2

x = 4/2

x = 2

When studying equations, it's important to practice solving different types of equations and understand the properties of equality. Here are some key points to remember:

- Always perform the same operations on both sides of the equation to maintain equality.
- Be mindful of special cases, such as dividing by zero or taking the square root of a negative number.
- Practice factoring and using the quadratic formula for solving quadratic equations.
- Check your solutions by substituting the values back into the original equation.

By mastering the skills of solving equations, you'll be better equipped to tackle more complex problems in algebra and beyond.

Grade 6 Curriculum Focal Points (NCTM)

Algebra: Writing, interpreting, and using mathematical expressions and equations

Students write mathematical expressions and equations that correspond to given situations, they evaluate expressions, and they use expressions and formulas to solve problems. They understand that variables represent numbers whose exact values are not yet specified, and they use variables appropriately. Students understand that expressions in different forms can be equivalent, and they can rewrite an expression to represent a quantity in a different way (e.g., to make it more compact or to feature different information). Students know that the solutions of an equation are the values of the variables that make the equation true. They solve simple one-step equations by using number sense, properties of operations, and the idea of maintaining equality on both sides of an equation. They construct and analyze tables (e.g., to show quantities that are in equivalent ratios), and they use equations to describe simple relationships (such as 3x = y) shown in a table.
