Translate the following sentence into an equation. Five times the sum of a number x and three is twelve.
Solve: y + (-16) = -12
Solve: -a/6 + 5 = 2
Solve: 3/5 y = -9
Solve: -6d = -42
Translate this into a sentence: 4n = 6(5 - n)
Solve, showing all work. 5(12 - 3p) = 15p + 60
3(y - 2) = 6(y - 1) - 3y
3a + 21 = 7 - 4a
