Solve for the given variable:

5k + 9 = 19

• k = 3

• k = -5

• k = 2

• k = 6

m - 7 + 5m = 11

• m = 6

• m = -2

• m = 4

• m = 3

The steps in solving 5b - 6 = 24 are: 

• Add 6 to both sides and divide both sides by 5
• Add 6 to both sides and multiply both sides by 5
• Subtract 6 from both sides then multiply both sides by 5
• Subtract 6 from both sides then divide both sides by 5
