How would i solve 5+x=15

5+x=15

You would solve it by first charging the 5 to a - 5.

5 - > - 5

With that - 5 you subtract it from 15.

15-5 = 10

Once you subtract, you should get 10 and then you divide both sides with x. (When a x is by itself it is 1x)

1x/1 = 10/1

Then you should get 10.

X=10

Answer: 10

Step-by-step explanation: You would subtract the 5 from both sides. x=10 should be left. Make sure you plug the 10 back into X to check your answer.
