Question
Solve the system of linear equations by substitution.

8x−13y=0
12x+3=y

Respuesta :

Answer:

(-39/148, -33/37)

Step-by-step explanation:

Let's choose the second equation, 12x + 3 = y, for our substitution.  Substitute (12x + 3) for y in the first equation, obtaining:

8x - 13y = 0  =>  8x - 13(12x + 3) = 0

Next, multiply out -13(12x + 3):  From the above equation we get

                          8x - 156x - 39 = 0

and this simplifies to -148x = 39  or  x = -39/148.

Substitute -39/148 for x in 8x - 13y = 0.  We get:

                              8(-39/148) + 3 = y, so that y = -33/37.

The solution of this system of linear equations is (-39/148, -33/37).
