What is the first step to solve 2x + 3 = 9?
Look for what needs to be done to isolate x.
True or False: To solve the equation x + 1 = 5, you need to add 1 to both sides.
Think about the opposite operation.
Solve for x in the equation 3(x - 2) + 9 = 2x + 6.
Remember to distribute before rearranging.
Find the value of y in the equation 6y - 4(2 - y) = 2(y + 6).
