Question

Addison worked 11 more hours this week than last week. In total, she worked 81 hours this week and last week. Using the equation 2h + 11 = 81, how many hours (h) did Addison work last week?
7
68
35
70

Answer 1

Make\[h\] the subject of the equation \[2h=81-11=70\] then solve for \[h\]

Answer 2

Subtract 11 from both sides and get that 2h is equal to 70:
2h=70.
Solve for h by dividing both sides by 2.
