x + 8x = 477 9x = 477 x = 53
8x+39 = 2x-15 6x = -54 x = -9
x=1, y=1
(4 ± i2) where i2 = -1
8x plus 4y equals 5 is 8x + 4y = 5.
If -8x+3=251, then 8x=-248. Therefore, x=-31.
8x + -2 = 10 8x = 12 x = 1.5
x + 8x = 477 9x = 477 x = 53
-8x + 6 = -58 -8x = -64 x= -64/-8 x = 8
x= -8
8x+39 = 2x-15 6x = -54 x = -9
x=1, y=1
Y-8x plus 9y equals 10y-8x.
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
(4 ± i2) where i2 = -1
8x plus 4y equals 5 is 8x + 4y = 5.
