Equations with Variables on Both Sides

Front

What is an equation with variables on both sides?

Back

An equation that has 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. Move all variable terms to one side of the equation. 2. Move constant terms to the other side. 3. Isolate the variable.

Front

Solve for y: 2y - 5 = y + 4

Back

y = 9

Front

Solve for k: 4k + 39 = 7k + 6

Back

k = 11

Front

Solve for y: 14y + 5 = 8y - 1

Back

y = -1

Front

Solve for y: 2y + 7 = y + 4

Back

y = -3

Front

Solve for x: 5x - 14 = 8x + 4

Back

x = -6

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 easier to solve.

Front

What is a constant in an equation?

Back

A fixed value that does not change, represented by numbers in equations.

Front

What is the first step in solving the equation 3x + 4 = 2x + 10?

Back

Subtract 2x from both sides to get x terms on one side.
