y-15=3x balakaksnzujsbhzbskndh

Answer 2

x = - 6 , y = - 3

Explanation:

y - 15 = 3x => y = 3x + 15 ------- ( 1 )

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

Substitute ( 1 ) in ( 2 ) :

-2x + 5 ( 3x + 15) = - 3

-2x + 15x + 75 = - 3

13x = - 3 - 75

13x = - 78

x = - 6

Substitute x in ( 1 ) :

y = 3x + 15

= 3 ( - 6 ) + 15

= - 18 + 15

y = - 3
