Answer: x = -3/2

Step-by-step explanation:

Hi, to answer this question we have to solve the system of equations:

2x +y =-3

y=4x+6

Substituting y=4x+6 in the first equation:

2x + (4x+6) =-3

Solving for x:

2x +4x+6 =-3

2x+4x =-3-6

6x =-9

x =-9/6

x = -3/2

In conclusión, the value of x is -3/2.

Feel free to ask for more if needed or if you did not understand something.
