That doesn't factor neatly. Applying the quadratic formula, we find two real solutions: (1 plus or minus the square root of 29) divided by 2
x = 3.192582403567252
x = -2.192582403567252
(3x - 4)(x - 1)
2/7x = 8x = 8 x 7/2x = 28
(5x - 3)(x + 8)
(x + 5)(x + 8)
(x + 4)(x + 8)
(7x - 8)(2x - 7)
7x+8
(7x + 8)(7x - 8)
7x + 8 = 10x - 2 ∴ 3x = 10 ∴ x = 10/3
56x^2 + 96x + 40
5x-8 + 7x 12x-8 12x = 8 x = 8/12 x= 2/3
7x+8=2 .....-8..-8 7x=-6 7x/7=6/7 x=6/7 In conclusion, 7(6/7)+8=2 I'm sure you meant: x = - (6/7) or -6/7 (not 6/7).
x=1
4x + 8 + 7x + 12 = 11x + 20
x(7x ^2 - 4x + 8)
7x + y = 8 Subtract 7x from each side of the equation: y = -7x + 8
7x + 8 = 36 - 8 = - 8 -------------- 7x = 28 7x/7 = 28/7 x = 4
