2 x + 5 = 15 x = ______

Answer 1

Step-by-step explanation: (Answers in bold )

24-(-14) using the keep change change rule you get 24 +14 = 38

-9*-5 =45 (negative times a negative = a positive )

31+x=15x subtract x from both sides

31=14x divide by 14

31/16 ---or---> 2.21

2x+5= 15x subtract 2x from both sides

5=13x divide by 13

5/13 or-------> 0.38
