Answer:
20x-8 ...last option
Step-by-step explanation:
Both equations have as the left hand side.
Then, in a situation like
we can deduce , since they both equal
So, we can set up the equation
The solutions are
From the second equation we know that y is one more than x, so we have
-8(2)+5-2(2)-4+5(2)
-16+5-4+10
-11-4+10
-15+10
5
-8x+5-2x-4+5x
-5x+1
