7.3 HW – Solving Equations with Variables on Both Sides

Tell which term you would add or subtract on both sides side of the equation so that the variable is only on one side. 1. 7x − 1 = 2x + 5 2. 3y + 1 = 4y − 6

_______________________________________ ________________________________________

3.10 − y = 2y + 3 4. 6x + 2 = 1 − x

Solve. 5. 3a − 10 = 4 + a 6. 5y + 4 = 4y + 5 7. b + 3 = 2b − 7

14. The difference of four times a number and five is the same

as three more than twice a number. Find the number. ___________________ 15. Fifteen more than twice the hours Carla worked last week

is the same as three times the hours she worked this week decreased by 15. She worked the same number of hours each week. How many hours did she work each week? ___________________
