What does it mean to solve an equation?

Back

To solve an equation means to find the value(s) of the variable(s) that make the equation true.

Front

What is the first step in solving the equation 3t = 27?

Back

Divide both sides of the equation by 3 to isolate the variable t.

Front

Solve for t: 3t = 27

Back

t = 9

Front

What is the process to isolate a variable in an equation?

Back

You can isolate a variable by performing inverse operations (addition, subtraction, multiplication, or division) to both sides of the equation.
