Back

The solution is x = 185.

Front

How do you show your work when solving 12y - 8 = 30.4?

Back

First, add 8 to both sides, then divide by 12.

Front

What does it mean to 'isolate the variable'?

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

What is the solution to the equation 12y - 8 = 30.4?

Back

The solution is y = 3.2.

Front

What is the second step in solving the equation 3x - 7 = 32 after adding 7?
