no..

anonymous · Answer

Okay lets get y=x+5 . Logically, y equals x plus 5. 
So plug this in for y into the *other* equation. 

5(x+5)+12=6x 
Distribute. 
5x+25+12=6x 
Simplify 
5x+37=6x
subtract 37 
5x=6x-37 
Get the x's on the same side (left) 
Minus 6 x then.
-x=-37 
Divide by -1
x=37 

Plug 37 in for x . And solve for your Y :]

y=37+5 
(came from y=x+5, with our 37 plugged in for x) 

y=42
