Solve each equation below for x. Show your work and CHECK your answer a. 3x + 2 = 2(x + 2) b. 5x − 6 = 9x − 1 − 5x
a. 3x + 2 = 2(x + 2) the idea is to get x by itself......simplify on the right
3x + 2 = 2x + 4 subtract 2x, 2 from each side
x = 2
b. 5x − 6 = 9x − 1 − 5x simplify on the right
5x - 6 = 4x - 1 add 6 to both sides, subtract 4x from both sides
x = 5
