8x - 3 =5(2x + 1)
30) 8x - 3 = 10x + 5 ..............G. Distributive property
31) -2x - 3 = 5 ........................A. Subtraction property
32) -2x = 8..............................B. Addition property
33) x = -4................................F. Division property
34)
3x^3 -5x^2 - 13x + 3 by x - 3
answer
D. 3x^2 + 4x - 1
35)
