Question

8x-6y = 30
8y-9x =60​

Answer 1

Answer

y=6 .35

x=8.51

Step by step explanation

8x -6y = 30

2(4x-3y) = 2×15

Cancelling 2 on both sides

4x-3y =15

4x=15+3y

x= (15+3y)/4

Substitute value of x in 2nd equation

8y -9x =60

8y-9[(15+3y)/4] = 60

32y-135 +27y=240

59y = 375

y =6.35 approximately

x= [15+3(6.35)]/4

= (15+19.05)/4

= 34.05/4

= 8.51 approximately
