Question

Solve y = 7x-3w for x

Answer 1

y=7x-3w
y+3w=7x
y+3w/7=x

Answer 2

`x=(y+3w)/(7)`

Explanation:

The given equation is

`y=7x-3w`

We need to solve this equation for x.

Isolate variable x to solve this equation for x.

Add 3w on both sides.

`y+3w=7x-3w+3w`

`y+3w=7x`

Divide both sides by 7.

`(y+3w)/(7)=(7x)/(7)`

Cancel out common factors.

`(y+3w)/(7)=x`

Interchange the sides.

`x=(y+3w)/(7)`

Therefore, the formula for x is
`x=(y+3w)/(7)`.
