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: 2(4x-3) - 8 = 4 + 2x

Back

x = 3

Front

Solve: 8w - 8 = -4w + 16

Back

x = 2

Front

What does it mean to isolate a variable?

Back

To manipulate an equation so that the variable is alone on one side of the equation.

Front

Solve for x: 4(1-x) + 3x = -2(x+1)

Back

x = -6

Front

What is the first step in solving the equation 7w + 5 = 3w - 15?

Back

Subtract 3w from both sides to combine like terms.

Front

Solve: 7w + 5 = 3w - 15

Back

x = -5

Front

What is a constant in an equation?

Back

A fixed value that does not change, represented by a number.

Front

Solve the equation: -8x - 8 + 3(x-2) = -3x + 2

Back

x = -8
