8 times 3 plus 32 equals 56. 8x + 32 = 56 8x + 32 - 32 = 56 - 32 8x = 24 8x / 8 = 24 / 8 x = 3

8x + 32 + 24 = 0 So 8x + 56 = 0 Subtract 56 from both sides: 8x = -56 Divide both sides by 8: x = -7

Take 3 from each side: 8x = 56 Divide by 8: x = 7 Next business?

- 8x + 8x = 0 so question is meaningless.

8x + 3 = 35 8x = 32 x = 4

X equals 9.

x2 - 8x - 40 = 0 ∴ x2 - 8x = 40 ∴ x2 - 8x + 16 = 56 ∴ (x - 4)2 = 56 ∴ x - 4 = ± 561/2 ∴ x = 4 ± 561/2 ∴ x = 4 ± 2 × 141/2 ∴ x ≈ {11.4833, -3.4833}

x + 8x = 477 9x = 477 x = 53

x = 2

x = -2

6x plus 3 equals 8x plus 14 when solved mathematically is equal to x = -5.5.
