Please help me solve them

Ok so the first thing to do would be get rid of the fraction. To do that multiply the ENTIRE equation but the denominator. Once all the numbers are multiplyed I think it’ll be easier for u to solve them :) or if u wanna solve them quick, download Photomath :)

1) x= 22

2) x= -2

3) x= -5

4) x= 7

+1,000)=g7e=mc2-g=7 because if you know algebra you should know g=7 to get your answer
