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?
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}
- 8x + 8x = 0 so question is meaningless.
8x + 3 = 35 8x = 32 x = 4
X equals 9.
x + 8x = 477 9x = 477 x = 53
5
6x plus 3 equals 8x plus 14 when solved mathematically is equal to x = -5.5.
-8x + 3 = 27 -8x = 27 - 3 -8x = 24 -x = 3 x = -3
x = 2
