Answer:
a=-85/4
b=53/4
Step-by-step explanation:
17x(5+a)=17xb+221. (1)
85+17xa=17xb+221
85+(17xa)-(17xb)-221=0
17xa-17xb=-136
17x(a-b)=-136
a-b=-8
a=-8+b. (2)
Replace a=-8+b to (1):
17x5x(-8+b)=17xb+221
85x(-8+b)=17xb+221
-680+85xb=17xb+221
-680+85xb-17xb-221=0
-68xb-901=0
-68xb=901
b=-53/4
Replace b=-53/4 to (2):
a= -8+(-53/4)= -85/4
