Question

3x-2/3y+7=5x-1/5y+16, 3x-15/x-9=6y-5/2y+3


please solve

Answer 1

Answer:

x = 3 ,  y = 2

Step-by-step explanation:

(3x - 2 ) (5y +16 )   = (5x -1) (3y +7)

15xy -10y +48x - 32 = 15xy -3y +35x -7

13x -7y -25 =0     equ (1)

(3x -15) (2y +3) = (6y -5) ( x -9)

6xy -30y +9x -45 = 6xy -5x -54y +45 =0

14x +24y -90 =0    equ (2)

0n solving (1) & (2)     by cross multiplication method

    x          y        1

-7      -25      13       -7

24     -90     14       24

x/1230    +y /820    =1/410

x = 1230/410             y = 820 /410

    =3                              =2
