Question

A set of equations is given below:

Answer 1

Answer:

x + 1 = 4x + 5

Step-by-step explanation:

To solve this set of equation you can just equalize them ot one another, as you can see they are already in Y form, which means that they have already been solved for Y, so that makes things easier for us, we just insert the second equation in the place of Y in the first one, and we can solve for "x".

Answer 2

The correct answer is A, or x + 1 = 4x + 5.  We used the substitution method to replace y with x + 1.
