Question

I need to know the solution

Answer 1

a. x=7
and
c. x=16
you can also get an app that is called script calculator that helps with that

Answer 2

For the first one, you have to get x by itself and make it positive. So divide both sides by -11. Then, you get x=-7. The answer is x=-7.

For the second one, get x by itself as a whole number. Multiply each side by 8. You get x=16. The answer is x=16. Hope this helps! ;)
