7y-x=5-5x make x subject of formulae

Answer 1

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.
