5x+20=70 solve for x

5x + 20 = 70         5x = 70 - 20         5x = 50           x = 50/5           x = 10 5(10) + 20 = 70      50 + 20 = 70               70 = 70 hope this helps :)

1st minus from 20. that cancels out. Then put it on the other side so it looks like 5x=70-20. simplify. 5x=50. next, divide by 5. 50/5=10. so x=10
