6.) 4x + 7 = 3x - 3
4x + 7 - 3x + 3 = 0 (Transposition)
x + 10 = 0 (Combine)
x = -10 (Transposition)
7.) 8x - 3 = x + 6
8x - 3 - x - 6 = 0 (Transposition)
7x - 9 = 0 (Combine)
7x = 9 (Transposition)
7x = 9 (Cancellation)
7 7
x = 9
7
8.) 5(x - 2) + 2x = 7(x + 4) - 38
5x - 10 + 2x = 7x + 28 - 38 (Simplify)
7x - 10 = 7x - 10 (Simplify)
7x - 7x - 10 + 10 = 0 (Transposition)
= 0
Good luck with your studies!
