How do you solve 4y plus x equals 8
x = 4 and y = 0
You cannot solve one equation in two unknowns.
-x + 4y = 8
6x = 32 - 4y and 4y - 8 = 6x so 32 - 4y = 4y - 8 ie 40 = 8y so y = 5 and x = 2
x = 4y - 2x = 6y + 84y - 2 = 6y + 8Subtract 4y from each side:-2 = 2y + 8Subtract 8 from each side:-10 = 2yDivide each side by 2:-5 = yx = 4y - 2x = -22
x = 4 and y = 0

You can't solve it. But you can simplify it to get: 4x+y=2
-x + 4y = 8

6x = 32 - 4y and 4y - 8 = 6x so 32 - 4y = 4y - 8 ie 40 = 8y so y = 5 and x = 2

x = 4y - 2x = 6y + 84y - 2 = 6y + 8Subtract 4y from each side:-2 = 2y + 8Subtract 8 from each side:-10 = 2yDivide each side by 2:-5 = yx = 4y - 2x = -22
-8 - 5y = 12 - 9y -8 + 4y = 12 4y = 20 y = 20/4 or 5
By definition: 4y-2 = 6y+8 4y-6y = 8+2 -2y = 10 y = -5 and by substituting this value into the equation x = -22
2x+4y = -8 4y = -2x-8 y = -1/2x-2 or y = -0.5x-2
It is:- 3x+4y = 8 4y = -3x+8 y = -0.75x+2 So the slope is -0.75 and the y intercept is 2
