Question

5x+20=70

solve for x

Answer 1

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

Answer 2

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 :)
