# What is the answer to y equals 4x plus 8?

y=4x+8.

Simply plug in **any** number you wish into x and then
calculate the corresponding y. For instance, if I said x was 2,
then y would be 4*2+8=16 and my answer would be the ordered pair,
(2,16).

### Solve by the substitution method 4x-5y equals -8 4x plus 40 equals y?

4x-5y = -8 4x+40 = y => y = 4x+40 Substitute the value of y into the top equation: 4x-5(4x+40) = -8 4x-20x-200 = -8 4x-20x = 200-8 -16x = 192 Divide both sides by -16 to find the value of x: x = -12 Substitute the value of x into the original equations to find the value of y: Therefore: x = -12 and y = -8

### 4x-y equals 32 4x plus 5y equals -16?

Presumably this is a simultaneous equation question in the form of: 4x-y = 32 4x+5y = -16 Subtract the bottom equation from the top equation remembering that a -- is equal to a + so 32--16 is +40 and that -+5y-y is -6y: -6y = 48 Divide both sides by -6 to find the value of y: y = -8 Substitute the value of y into the original equations to find the value of x…
