Question

7+8=x/3
how do i solve this

Answer 1

`x=45`

Explanation:

`7+8=(x)/(3)`

Combine the 7 and 8:

`15=(x)/(3)`

Multiply both sides by 3:

`45=x\\x=45`

Answer 2

Because this is addition, you must reverse the process by (maybe) doing x/3 and 8/1 or 7/1. Cross multiply the numerators and denominators.
