I think the answer is (-6,30) unless I messed up somewhere
160 adults and 80 students seems to be correct
Hi there!
Since both 4x and 20 can be divisible by 4 and is greatest able to be divisible by 4, we can divide the 4 and put it outside of the parenthesis in order to factor:
4x / 4 = x
20 / 4 = 5
4 (x + 5)
would be your answer.
Hope this helps!

rock climbers minute of climbing = x
2x + x + 50
