Answer:

x = -2

y = 3

Step-by-step explanation:

from above equation we get ,

=》y = 3x + 9

now ,

by second equation,

=》2x + 3y = 5

=》2x + 3 × ( 3x + 9 ) = 5

( since, y = 3x + 9 , by equation 1 )

=》2x + 9x + 27 = 5

=》11x = -22

=》x = -2

putting value of x in equation 1 ;

=》 y = 3x + 9

=》 y = 3 × ( -2 ) + 9

=》 y = -6 + 9

=》 y = 3
