Question #72c73

Answer 1

`x =3,y =2`

Explanation:

`3x-2y = 5` --->a
`2x+3y=12` ---->b

to eliminate `y`, multiply `a` by 3 and `b` by 2 and add both equations

`9x - 6y = 15`
`4x +6y = 24`
#-------------------

`13 x =39`
`x =39/13 =3`

to eliminate `x`, multiply `a` by 2 and `b` by 3 and deduct both equations

`6x - 4y = 10`
`6x +9y = 36`
#-------------------

`-13 y =-26`
`y =(-26)/-13 =2`
