1 Two-Step Equations THINK of Hands-On Equations. Isolate the variable. Since algebra is working backwards, do the order of operations in reverse. UNDO addition and subtraction before multiplication and division. Solve and justify each step A cable television company charges $24.95 per month for basic cable service and $6.95 per month for each additional premium channel. If Sam’s monthly bill is $45.80, how many premium channels is he receiving?

2 Solve and justify each step.
Jane’s cell phone plan is $20 per month plus $0.35 per minute for each minute over 200 minutes of call time. If Jane’s cell phone bill is $69.00, for how many extra minutes was she billed?
