Equations with Variables on Both Sides

Front

What is an equation with variables on both sides?

Back

An equation that contains variables on both the left and right sides, requiring manipulation to isolate the variable.

Front

How do you solve an equation with variables on both sides?

Back

1. Simplify both sides of the equation. 2. Move all variable terms to one side and constant terms to the other. 3. Isolate the variable.

Front

Solve: 5y + 34 = -2(-7y + 1)

Back

y = 4

Front

What does it mean to isolate a variable in an equation?

Back

To manipulate the equation so that the variable is alone on one side, making it easy to determine its value.

Front

Solve: -6(1 - 6r) = -2(r + 3)

Back

r = 0

Front

What is the first step in solving the equation 3 - 5x = -9 + x?

Back

Front

Solve: 3 - 5x = -9 + x

Back

x = 2

Front

What is the purpose of checking your solution in an equation?

Back

To verify that the solution satisfies the original equation, ensuring it is correct.

Front

Solve: 12x - 15 = 3(2x + 3)

Back

x = 4

Front

What is a constant in an equation?

Back
