Answer:

Explanation:

3x+y=9

y=9-3x

4x-3y=6

4x-6=3y

y=(4x-6)/3

y= 4/3x-2

9-3x=4/3x-2

9+2=4/3x+3x

11=13/3x

x=11*3/13

=2.53

y=9-3*2.53

=1.41

Answer:

multiply the first equation with 3, then add the two equations, you'll get the value of x, by putting the value of x in any of the two equations, find y, answer should be this,

x = 33/13,

y = 18/13
