X=1 and y=4. first I did 
3x+2y=11
y=5x-1
and 3x+2(5x-1)=11
=3x+10x-2=11
=13x-2=11
cancel 2 out
13x=13
x=1. then simply add x in the original y equation,
y=5x-1
y=5(1)-1
y=5-1
y=4.
check your work
3(1)+2(4)=11
4=5(1)-1 
again X=1 AND Y=4 
Hope this helped

8x - 9 - 5x = 3x - 36 - 18x
makkiz [27]

Answer:

8x - 9 - 5x = 3x - 36 - 18x \\ 8x - 5x - 9 = 3x - 18x - 36 \\ 3x - 9 =  - 15x - 36 \\ 3x =  - 15x - 36 + 9 \\ 3x =  - 15x - 27 \\ 3x +  - 15x =  - 27 \\  - 12x =  - 27 \\ x =  \frac{ 27}{12}
