Question

By elimination method solve this equation..
2x+3y=5; 3x-9=4y ​

Answer 1

Answer:

2x+3y=5(eq-1)

3x-9=4y or 3x-4y=9

(2x+3y=5)4

( 3x-4y=9)3

8x+12y=20

9x-12y=27

=17x=47

so, x=47/17

substituting x value in eq 1 we get

2*47/17+3y=5

3y=5-94/17

3y=85-94/17

3y=-9/17

y=-9/17*3

y=-3/17

thus x=47/17 and y=-3/17
