Find the value of x in the system, using substitution y=2x; 4x-y=-4

x=-2

y=-4

Step-by-step explanation:

y=2x;

4x-y=-4

Substitute y =2x into the second equation

4x - (2x) = -4

4x - 2x = -4

Combine like terms

2x = -4

Divide by 2

2x/2 = -4/2

x=-2

Now we need to find y

y = 2x

y =2(-2)

y=-4

its a trick question
