Solve the following systems of linear equations using any algebraic method.If possible,check your solution.
1)2x+5y=3
X3y=7
2) 3y=112x
3x=y11
3)8x6y=14
12x9y=18

#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.
