• To isolate the variable

In the equation y - 21 = 43, what should be added to both sides to isolate y?

• 21

• 43

• 64

• 0

What is the value of y in the equation y - 21 = 43?

• 43

• 21

• 22

• 64

How can you verify the solution y = 64 for the equation y - 21 = 43?

• By dividing 64 by 21

• By multiplying 64 by 21

• By subtracting 21 from 64

• By adding 21 to 64

In the equation 90 = g - 15, what should be added to both sides to isolate g?

• 90

• 15

• 105

• 0

What is the value of g in the equation 90 = g - 15?

• 15

• 90

• 105

• 75

How can you verify the solution g = 105 for the equation 90 = g - 15?

• By multiplying 105 by 15

• By subtracting 15 from 105

• By adding 15 to 105

• By dividing 105 by 15
