30 minutes is 1/2 an hour so 16 x 2 = 32 the phone charges at 32% per hour.
1. Multiply the number of hours by the rate and add the original 10% to that for total charge:
Y = 0.32h + 0.10
2. The phone charges at 16% every thirty minutes which is a half hour so you double the rate it charges to get the rate per hour. The phone charges at 32% per hour that it is charging.
Isolate the x. Note the equal sign. What you do to one side, you do to the other.
Subtract 9 from both sides
x + 9 (-9) = -4 (-9)
x = -4 - 9
x = -13
-13 is your solution
