Question 13 is 14 x is 14

I'll solve 11-14 since they are fairly simple problems once you get to understand them :)

  • Remember: what you do to one side of the equation, you do to the other.
  • To get everything on one side of the equation, you perform the opposite operation.
  • Say for example, 4x = 8. Since you are multiplying 4 * x, the opposite operation of multiplication is division, so in this case you would DIVIDE both sides by 4.

11) 15 = 6.5 + x

  • The opposite of addition, 6.5 + x, is subtraction, so subtract 6.5 from both sides.

15 - 6.5 = x

  • 8.5 = x, which is the same as x = 8.5.

12) -3 + x = -17

  • The opposite of subtracting is addition, so add 3 to both sides.

x = -17 + 3

  • x = -14

13) 7x = -98

  • You have 7 * x, which is multiplication, and the opposite of multiplication is division, so divide both sides by 7.

x = -98/7

  • x = -14

14) x/-3 = -7

  • The opposite of division is multiplication, so multiply both sides by -3.

x = -7 * -3

  • x = 21

Hope this helped, good luck!
