How would you isolate the variable in the following equation?

n + 4 = 12

• Add 4 to both sides, the answer is 16

• Divide both sides by 4, the answer is 3

• Subtract 4 from both sides, the answer is 8

• Multiply both sides by 4, the answer is 48

How would you isolate the variable for the following equation:

x - 7 = 2

• Divide both sides by 7, the answer is 125

• Add 7 to both sides, the answer is 9

• Add 2 to both sides, the answer is 9

• Multiply both sides by 7, the answer is 14

Which choice models this situation? Marcus needs to sell 25 tickets to a fundraiser by Friday. So far, he has sold 9 tickets. How many tickets does he still need to sell?

• t - 9 = 25

• t + 9 = 25

• 9t = 25

• t/9 = 25
