Answer:
y=7 and x=-8
Step-by-step explanation:
Isolate x in the first equation:
10x=-17-9y
x=(-17-9y)/10
Substitute into the second equation:
7*((-17-9y)/`10)+10y=14
-119/10+37y/10=14
-119+37y=140
37y=259
y=7
Putting this into the first equation, we get that x=-8
Answer:
a^7
Step-by-step explanation:
=(a^3)^3/a^2
