Question

If 4x+y= z solve for x.

Answer 1

To get the answer, we have to isolate x on the left side. first subtract y, to get 4x=-y+z. then divide both sides by 4. So your final answer would be x=(z-y)/4. Z-Y is being devided by 4.

Answer 2

Here is the equation:

`4x+y=z`

You need to find x. To do that, the variable must be alone on one side. On the right side, you have:

`4x+y`

To leave 4x by itself, you need to remove y by doing the opposite sign of it. Since it's +y, you need to -y(subtract y) from both sides.

`4x+y-y = z-y \\ 4x=z-y`

Now the variable is alone. You have 4x and you need to find x alone. To do that, you need to divide both sides by 4.

`(4x)/(4) = (z-y)/(4)`

Your answer is:

`x = (z-y)/(4)\ \checkmark`
