Back

b = 3

Front

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

Back

To isolate a variable means to get the variable alone on one side of the equation.

Front

Solve: -5t + 9 = 24

Back

t = -3

Front

What is the second step to solve the equation 2d + 7 = 9?

Back

Subtract 7 from both sides, then divide by 2.

Front

Solve: 2d + 7 = 9

Back

d = 1

Front

What is the purpose of using inverse operations in solving equations?

Back

Inverse operations are used to undo the operations applied to the variable, helping to isolate it.
