Question

How do you solve `x/4 -3=2`?

Answer 1

x = 20

Explanation:

Begin by leaving the x term on the left and placing numeric terms on the right.
We can do this by adding 3 to both sides of the equation.

`x/4cancel(-3)color(red)cancel(+3)=2color(red)(+3)`

we now have `x/4=5`

which is the same as `x/4=5/1`

and cross-multiplying gives.

`(1xx x)=(4xx5)rArrx=20`

a quick check shows that `20/4-3=5-3=2`
