Sophia Goodwin · Answer 1

Let's call

x = number of hours worked by Kyle in his old job.

y = number of hours worked by Kyle in his new job.

Writing the system of equations:

x + y = 54

5x + 7y = 338

Solving the system of equations:

5 (54-y) + 7y = 338

270-5y + 7y = 338

2y = 338-270

y = 68/2 = 34

Therefore, Kyle worked 34 hours in his new job.
