Shorter Practice Adding and Subtracting Equations

What is the main task when evaluating equations?

• to add numbers

• to get the variable by itself

What inverse operation would you use to solve this problem?
 g - 57 = 113

• subtract
• add

What does inverse mean?

• The same
• The opposite

5 + a = 37

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

3+x=5

• 1

• 2

• 3

• 0

s + 42 = 75

• 33
• 117
• 36
• 43

y - 71 = 211

• 280
• 140
• 282
• 380

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

x - 10 = 12

• 22
• -22
• 2
• -2
