We know what y equals. 6. we implement the 6 in the place of the y. this is what that looks like.
2x+3(6)=36
we then multiply 3 by 6 and get 18
2x+18=36
We move the 18 over to the other side, making it negative
2x=36-18
We then subtract
2x=18
from here we are trying to isolate the 2x. The opposite of multiplication (because the 2 is trying to multiply the x) is division. so we divide by 2 to cancel the 2x and make it just x. we do this on both sides of the equal sign
2/2x=18/2
this gives us...
x=9
The correct answer is
x=9
y=6
