-8x + 6 = -58 -8x = -64 x= -64/-8 x = 8
3 is a factor and dividing by 3 gives x + 15 = 8x
x2-8x+15 = (x-3)(x-5)
No because the discriminant is less than zero.
If that's 15x2, the answer is (3x + 4)(5x - 4)
If that's -8x, the answer is (x - 4)(x - 4) or (x - 4)2 If that's +8x, the answer is (x + 4)(x + 4) or (x + 4)2
basic algebra -8x + 6 = -58 -8x = -64 x = (-64/-8) x = 8
8x + -2 = 10 8x = 12 x = 1.5
x + 8x = 477 9x = 477 x = 53
x= -8
8x+39 = 2x-15 6x = -54 x = -9
Subtract 7x from each side: x - 2 = -9Add 2 to each side: x = -7. Each side equals -58, job done.
x=1, y=1
Y-8x plus 9y equals 10y-8x.
-8x + 3 = 251 -8x = 251 - 3 -8x = 248 -x = 248 ÷ 8 -x = 31 x = -31
8x = 2x + 15 6x = 15 x = 15/6 = 2.5
4x + 3y = 8x + y so 3y - y = 8x - 4x ie 2y = 4x so y = 2x
8x plus 4y equals 5 is 8x + 4y = 5.
