Step-by-step explanation:
I assume
SR = 2x + 23
RQ = x + 21
if that is true, then the situation is completely simple :
14 = (2x + 23) + (x + 21) = 3x + 44
3x = -30
x = -10
SR = 2×-10 + 23 = -20 + 23 = 3
RQ = -10 + 21 = 11

Answer:
Step-by-step explanation:
y²-y-4x=0
differentiate w.r.t. x
2y*y^1-y^1-4=0
(2y-1)y^1=4
y^1=4/(2y-1)
