Answer:
20
Step-by-step explanation:
Let's start by rewriting the second equation in terms of "x":

Subtract y from both sides:

Now, substitute "5-y" for "x" in the first equation:

Note that:


Cancel out like terms:

Subtract 25 from both sides:

Divide both sides by -10

Now, substitute this value back into either of the equations to solve for x.

Add 15/2 to both sides:

Now, find the difference:

15.2
16 + 12 + 8 + 22 + 25 + 8 = 91 / 6 = 15.16 = 15.2
Step-by-step explanation:
2x-10x= -4y-y
-8x= -5y
cancel (-) on both sides we get
8x=4y
