Respuesta :

Answer:

B.) x² + 3x = 4

Step-by-step explanation:

To find the answer, you need to (1) isolate "y" in the first equation and then (2) plug the rearranged first equation into the second equation.

(Step 1)

2y = 6x                     <----- Original first equation

y = 3x                        <----- Divide both sides by 2

(Step 2)

x² + y = 4                  <----- Original second equation

x² + (3x) = 4              <----- Plug 3x in for "y"
