Question

x/5-y/4=0;3x+1/2y=17​

Answer 1

x/5-y/3=0

3x-5y=0..............(1)

The next equation seems incorrect.

Answer 2

Answer:

x = 3.4125 aprrox. 3.41, y = 1.53

(x,y) (3.41,1.53)

please mark me as brainiest. Thanks! ;)

Step-by-step explanation:

4x-5y / 20 = 0.3(mulitply top equation by 20 to remove the denominator)

3x+0.5y = 17

4x-5y = 6  (times 3)

3x+.5y = 17 (times 4)

12x-15y = 18

12x+2y = 68

-15y-27 = 18-68

= -15y-27 = -50

= -15y = -23

y = -23/-15

y = 1.53

12x -15(1.53) = 18

12x-22.95 = 18

12x = 18+22.95

12x = 40.95

x = 40.95/12 = 3.4125
