 * Solving Equations by Addition **

What number would you add to both sides to solve each equation?
 * 1. ** x - 3 = 11
 * 2.** d - 1 = 5
 * 3.** n - 7 = 8
 * 4.** m - 4 = 8
 * 5.** y - 15 = 3
 * 6.** z - 10 = 1
 * 7.** x - 15 = 3
 * 8.** y - 19 = 1
 * 9.** t - 24 = 2

What number would you add to both sides of these equations to solve them?
 * 10. ** x + 6 = 13
 * 11.** c + 1 = 8
 * 12.** y + 2 = 7
 * 13.** m + 5 = 5
 * 14.** x + 3 = 9
 * 15.** z + 7 = 10

Solve these equations.
 * 16.** m - 5 = 4
 * 17.** n - 3 = 2
 * 18.** p - 7 = 3
 * 19.** r - 7 = 9
 * 20.** s - 5 = 3
 * 21.** t - 8 = 5
 * 22.** p + 11 = 19
 * 23.** y + 2 = 3
 * 24.** r + 8 = 12
 * 25.** p + 5 = 11

//Solve the following equations.//
 * 26. ** m + 12 = 22
 * 27.** n + 15 35
 * 28.** x + 7 = 17
 * 29.** y + 11 = 33
 * 30.** y + 13 = 33
 * 31.** p + 17 = 37
 * 32.** x - 12 = 22
 * 33.** y - 10 = 18
 * 34.** m - 15 = 25
 * 35.** n - 11 = 33
 * 36.** x - 21 = 31
 * 37.** y - 9 = 24
