3x + 11y = 34.5
9x – 7y = -16.5 Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! 3x + 11y = 34.5...................1
9x – 7y = -16.5...................2
..
multiply (1) by -3
-9x-33y=-103.5
add this to (2)
-7y-33=-16.5-103.5
-40y=-120
/-40
y =3
..
plug value of y in 1
3x+33=34.5
3x=34.5-33
3x=1.5
x=1.5/3
x=0.5
