Y= x + 2 2x - y = -4 solve the system of equations using substitution. a) (-2,-4) b) (-2,0) c) (-6,-4) d) (-6,8)

For this case we must solve the following system of equations:

So, we substitute the first equation in the second one:

We consider by law of signs of multiplication that:

Different signs are subtracted and the sign of the major is placed:

We look for the value of the variable "y":

Thus, the solution of the system is given by:

Option B

depending on others is critical to survival. my source is apex!

step-by-step explanation:

answer: 0,6

step-by-step explanation:

this would make it the y intercept.
