16 + 4x + 2x - 3x + x = 0
First, simplify 16 + 4x + 2x - 3x + x to get 16 + 4x. / Your problem should look like: 16 + 4x = 0
Second, subtract 16 from both sides. / Your problem should look like: 4x = -16
Third, divide both sides by 4. / Your problem should look like: x =
Fourth, simplify

to get 4. / Your problem should look like: x = -4
Answer:
x = -4
