1 sec

Answer 3

ohhh is it A?

Answer 4

nope...
x/5 = -6 + 3
x/5 = -3 --- multiply both sides by 5
x = (5)(-3)
x = -15

you see, if you multiply x/5 by 5, the 5's cancel leaving you with just x...but what you do on one side of the equal sign, you have to do on the other...so then you multiply -3 by 5 giving you : x = -15
any questions ?
