What does 'isolating the variable' mean in solving equations?

Back

It means to get the variable alone on one side of the equation.

Front

Solve for p: 7p + 9 = 40.5

Back

p = 4.5

Front

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

Back

To undo the operations applied to the variable and isolate it.
