Answer:
The answer to your question is RQ = 3
Explanation:
Data
SR = x + 7
RQ = x + 4
SQ = 9
Process
1.- Write an equation that helps to solve this problem
SQ = SR + RQ
- Substitution
9 = (x + 7) + (x + 4)
- Solve for x
9 = x + 7 + x + 4
9 = 2x + 11
9 - 11 = 2x
-2 = 2x
x = 2/-2
x = -1
2.- Find the length of RQ
RQ = x + 4
= -1 + 4
= 3
