Question

Hello,

Answer 1

Answer:

value of x = -2

value of y = 1

Step-by-step explanation:

here's the solution :-

the given equations are :

=》-4x - 4y = 4

=》6x + 4y = -8

adding both equations, we get ;-

=》-4x - 4y + 6x + 4y = 4 - 8

=》2x = -4

( positive and negative 4y get eliminated )

=》x = -4 / 2

=》x = -2

plugging the value of x in equation 2 we get ,

=》6x + 4y = -8

=》(6 × -2) + 4y = -8

=》-12 + 4y = -8

=》4y = -8 + 12

=》y = 4 / 4

=》y = 1
