Back

v = 19

Front

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

Back

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

Front

Solve: -4x + 1 = 21

Back

x = -5

Front

What is the second step to solve the equation -3x + 5 = -16?

Back

Subtract 5 from both sides to isolate the term with x.

Front
