7y-x=5-5x make x subject of formulae
To make x the subject of the formula, we can rearrange the equation as follows:
7y - x = 5 - 5x
First, let's get rid of the x on the right side of the equation. We can do this by adding 5x to both sides:
7y - x + 5x = 5
Combine like terms:
7y + 4x = 5
Now, let's isolate x by subtracting 7y from both sides:
4x = 5 - 7y
Finally, to solve for x, divide both sides by 4:
x = (5 - 7y) / 4
Therefore, x is the subject of the formula x = (5 - 7y) / 4.
