Question

How do you solve `x/(x+2)= 15/25`?

Answer 1

`x=10`

Explanation:

Given
`color(white)("XXX")x/(x+2)=15/25`

Multiply both sides by `25(x+2)`
`color(white)("XXX")25x = 15x+30`

Subtract `15x` from both sides
`color(white)("XXX")10x=30`

Divide both sides by `10`
`color(white)("XXX")x=10`
