Question 372940: I have pulled my hair out trying to learn this stuff!! If anyone could help me I'd so appreciate it!! thank you!!
Solve using the elimination method. Show your work. If the system has no solution or an infinite number of solutions, state this.
3x + 11y = 34.5
9x – 7y = -16.5

Answer by mananth(16949)   (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
