x=10
x2 + 6x - 110 = 0 ∴ x2 + 6x = 110 ∴ x2 + 6x + 36 = 146 ∴ (x + 6)2 = 146 ∴ x + 6 = ±1461/2 ∴ x = -6 ±1461/2 ∴ x ≈ 6.083, 18.083

5x+15 = 6x-10 5x-6x = -10-15 -x = -25 x = 25
x=10
6x + 10 + 4x = 5010x + 10 = 5010x = 40x = 4
If 6x + 10 = 11x , then x=2.
10+12x=-14 -14-10=12x 12x=-24 x=-2
x2 + 6x - 110 = 0 ∴ x2 + 6x = 110 ∴ x2 + 6x + 36 = 146 ∴ (x + 6)2 = 146 ∴ x + 6 = ±1461/2 ∴ x = -6 ±1461/2 ∴ x ≈ 6.083, 18.083

3x + 6x +1 = 10 9x = 10 - 1 9x = 9 x = 1
8x+2=6x+10 8x-6x=10-2 2x=8 x=4 Therefore, x=4.
5x+15 = 6x-10 5x-6x = -10-15 -x = -25 x = 25
6x + 10 = 72 6x = 72 - 10 x = 62/6 x = 10.3333
