Answer: 10+12x=58
Explanation:
The equation would be 10+12x=58, where x is the amount of additional hours babysitting besides the first hour.
To solve: move terms to one side (subtract 10) so you'd get 12x=48
The answer to this equation would be x=4 (you divide by 12)
To check if correct: plug in 4, to get 10+12(4)=58 which is 10+48=58 which gets 58=58
So the time worked was a total of 5 hours since you have to add on the first hour, but the solution to your equation represents just the amount of additional hours worked besides the first hour.
