Question

Last week, Kevin studied 12 more hours than Jason. If they studied for a combined total of 54 hours, how many hours did Jason study for last week?

Answer 1

Jason studied for 21h and Kevin studied for 33h.

Explanation:

x= number of hours that Jason studied for

x+12 = number of hours that Kevin studied for

x+(x+12)=54 --> 2x+12=54 --> 2x=54-12 --> 2x=42 --> x=42/2 -->x=21
