Question

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

Answer 1

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.

Answer 2

Answer:

$x=45$

Step-by-step explanation:

$7+8=\frac{x}{3}$

Combine the 7 and 8:

$15=\frac{x}{3}$

Multiply both sides by 3:

$45=x\\x=45$
