8x + 6 = 3x - 4
8x = 3x - 4 - 6
8x = 3x - 10
8x - 3x = -10
5x = -10
5x/5 = -10
x = -10/5
x = -2

If -8x+3=251, then 8x=-248. Therefore, x=-31.
8x+30=4x+18 -4x -4x 4x+30=18 -30 -30 4x=-12 4x/4=-12/4 x=-3
8x + 6 = 2x + 24 To solve, collect like terms on each side; collect the x's on the left, the numbers on the right: 8X + 6 = 2x + 24 8x - 2x = 24 - 6 6x = 18 6x / 6 = 18 / 6 x = 3
8x + 3 = 50 8x = 47x = 47/8x= 5 and 7/8ths
8x - 9 = 11x + 12 8x = 11x + 21 -3x = 21 x = -7
