Question

If 4x - 3y = -18 and 6x + 7y = -4, then what is the value of y?

Answer 1

Answer:

4x-3y = - 18 _ (1)

6x + 7y = - 4_ (2)

Step-by-step explanation:

Now multiplying (1) by 7 and (2) by 3 we get

28x - 21y = - 126 (3)

18x + 21y = - 12 (4)

Now adding both we get 46x = - 138

X = - 3

Now 3Y = 4(-3)+18 = 6

Y= 2
