For this case we have the following system of equations:

To solve, we follow the steps below:

We multiply the second equation by -4:

We add the equations:

Equal signs are added and the same sign is placed.

We look for the value of the variable “x”:

Thus, the solution of the system is:

Answer:Answer:x= 7/2 y = 7/6

Step-by-step explanation:4x – 12y = 0

x + 3y = 7

Multiply the second by( -4) to

eliminatethe X variable4x – 12y = 0

-4x -12y= -28

ADD BOTH

-24y=-28

Divide both by -24

y= 28/24

y=7/6

Plug y into second equation

x + 3y = 7

x+ 3(7/6) = 7

x+21/6=7

x+7/2=7

x=7-(7/2)

x=( 14/2) – (7/2)

x= 7/2
