Alright,
-9/10x + y = 1 1/10
Answer:
the answer is C
Step-by-step explanation:
hope this helps
Answer: No.
Step-by-step explanation: Sub -1/2 in for u in the equation:
8(-1/2) - 1 =6(-1/2)
=-4-1 = -3
=
-5=-3 which is false, so it is not a solution
Answer:
x=2 y=-3
Step-by-step explanation:
We first need to isolate x to get x+2y=-4:x=-4-2y
-4-2y-2y=8
simplify:
-4-4y=8.
We can also do the same for y which is -4-4y=8:y=-3
for the x, we can now substitute it to give us:
x=-4-2(-3)
-4-2(-3)=2
x=2
So, our answers are x=2 and y=-3
