What value of m would satisfy the equation?

-10(2m + 1) = -50

• m= 2

• m = -7

• m = 5

• m = -2

Solve.

m-7+5m = 11

• m = -4

• m = 6

• m = -2

• m = 3

Solve.

15c + 12 - 9 - 11c =43

• c =-8

• c= 9

• c = 10

• c = -9

• Add 7 to both sides. Solution is x=19.

• Subtract 7 to both sides. The solution is x=5.

• Multiply both sides by 7. The solution is x = 84.

• Subtract 12 on both sides. The solution is x=-5.

What is the first step to solve this equation:

-3x - 11 = 44

• Add 3 to both sides

• Add 11 to both sides

• Subtract 11 from both sides

• Divide by -3 on both sides
