Question 478503
-x + 2y   = 8
-x + 10y  = 48

I multiplied equation 1 by -1.

x - 2y = -8

then add to equation 2.

x  -  2y = -8
-x + 10y = 48

Next we add the two equations to obtain:

8y  =  40
y = 5

Now we can solve for x in equation one.
-x + 2(5)  = 8
x = 2

So x = 2 and y = 5.

We can check this in equation 2.

-(2) + (10)(5)  = 48,
