I need to answer more questions to pm so i’m doing this
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
