1. 4x + 3y=17
3x - 4y + 6 = 0



and plz follow ​

Answer 1

x=2,y=3 this is answer

Answer 2

Answer:

(4x + 3y=17)*3

12x+9y=51-------- 1

(3x - 4y  = -6)*4

12x - 16y= -24------2

add 2 and 1

 12x - 16y= -24

+12x+9y=51

      -7y=27

y= -27/7

y=3.86

substitute y value in 1

12x+9(3.86)=51

12x+34.74=51

12x=51-34.74

x=16.26/12

x=1.355
