5 + a = 37

• a = 37/5
• a = 42
• a = 185
• a = 32

- 12 + x = 11

• x = -1
• x = - 132
• x = 23
• x = - 11/12

x - 5.5 = 13.53

• x = 8.03
• x = - 8.03
• x = - 19.03
• x = 19.03

y+25=80
What steps do you need to solve this problem?

• Add 25 to both sides
• Subtract 25 to both sides
• Divide 25 on both sides
• Multiple 25 on both sides

3+x=5
