Answer:
5
Step-by-step explanation:
Alright so this problem is like that other one i did where line RQx2 is equal to line SU
First we set up an equation
x+3=x-2
because line RQ is only 1/2 of line SU we multiple its side by 2 to get the new equation of
x+3=2x-4
step 1 subtract each side by 2x
-1x+3=-4
step 2 subtract each side by 3
-1x=-7
divide each side by -1
x=7
Next we plug in x (7) so 7-2=5
line RQ=5
