Front

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

Back

Isolating a variable means to manipulate the equation so that the variable is on one side and all other terms are on the other side.

Front

Solve for c: 3c + 5 = 23

Back

c = 6

Front

What is the second step to solve the equation 6w - 1 = 11?

Back

Add 1 to both sides of the equation.

Front

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

Back

Inverse operations are used to undo operations and isolate the variable.
