Question

solve the system of equations using substitution. y = 4x 6 y = 2x (–3, –6) (6, 3) (3, 6) (1, 2)

Answer 1

Missing sign in the first equation.
I think it should read:
y=4x-6
y=2x

Please confirm before more details can be provided.

Answer 2

Answer:

Your answer is (-3,-6)

Step-by-step explanation:

y = 4x+6

y = 2x

Substitute the first equation's y with 2x.

2x = 4x+6 → -2x = 6 → -2x/-2 = 6/-2 → x =  -3

Now substitute -3 into the first equation.

y = 4(-3)+6 → -12+6 → y = -6
