#2:
2x + 3y = 11
3x - y = -11
multiply #2 by 3 and add:
2x+3y = 11
9x - 3y = -33
---------------
11x = -22
x = -2
now figure y: 5
Do the others likewise. To check your answers, just plug in the values and make sure the equations still balance.
Solve the following systems of linear equations using any algebraic method.If possible,check your solution.
1)2x+5y=3
X-3y=7
2) 3y=11-2x
3x=y-11
3)8x-6y=14
12x-9y=18
