Question

Solvef for x and y: 8x-3y=5xy, 6x-5y=-2xy

Answer 1

Answer:

(8x-3y=5xy ) - eq1. × 3

(6x-5y= -2xy). -eq2. × 4

using elimination method

24x- 9y = 15xy

24x- 20y= -8xy

- + +

________________

11y = 23xy

11= 23x

11/23=X

put the value of X in eq1

8×11/23 -3y= 5 y×11/23

88/23-3y= 55y/23

88/23= 55y/23+3y

88/23=124y/23

y = 88/23×23/124

y. = 88/124

y. =. 22/31
