3.  A. 10x + 3 = 33 - 3 -3 10x = 30 10 10 x = 3 B. -47 = 3x – 50 + 50 + 50 3 = 3x 1 = x

4.  C. 15y + 31 = 61 -31-31 15y = 30 15 15 y = 2  D. -35 = 2p + 10 -10 -10 -45 = 2p -22.5 = p

6.  C. -4.2 = + 1.8-1.8 -6 = m/2 -12 = m  D. - 3 = 10 + 3 + 3 x/-4 = 10 x = -40

8.  15 + 6 b = 39 -15 -15 6b = 24 6 6 b = 4 per roll
