For the following system, use the second equation to make a substitution for y in the first equation.

2x + y = 5
y + 3 = 2x

2x + 2x - 3 = 5
2x + 3 - 2x = 5
2x + 2x + 3 = 5

Respuesta :

Answer:

It is A

Step-by-step explanation:

2x + y = 5

y + 3 = 2x

From equation 2:

y = 2x - 3

Substituting in the first equation:

2x + 2x - 3 = 5.

Answer:

2x + 2x - 3 = 5.
