Okay, for this one I would use elimination:
8x+(-2y)-10
or
8x-2y=10
2x=4y
x=2y
8(2y)-2y=10
16y-2y=10
14y=10
y=5/7
x=10/7 or 1 3/7. Hope it help!
Answer:
9.33
Step-by-step explanation:
12.44=311/25
(3/4)×(311/25)=(3×311/4×25)=933/100=9.33
-2=-1/6(3)+b
-2=-0.5+b
-1.5+b
y=-1/6 -0.5
by solving the first equation you'll get x= -24/13
if you solve the second option (B) then you'll the same result i.e x=-24/13
so option C is correct
The answer is 9. Thank you for your time
