(2, 3)

Respuesta :

Answer:

The answer to your question is (3, 0)

Step-by-step explanation:

Data

              4x  +  2y  = 12                 Equation l

                x  -    y   = 3                   Equation ll

Process

To solve this problem use the elimination method

1.- Multiply equation ll by 2

              4x  +  2y  =  12

              2x  -  2y  =    6

              6x      0   = 18

2.- Solve for x

                        6x = 18

                          x = 18/6

                          x = 3

3.- Substitute x in equation ll to find y

                3  -  y  = 3

-Solve for y

                    -y = 3 - 3

                     y = 0

4.- Write the solution

                   (3, 0)

A
4(3)+2(0)=12+0=12
3-0= 3
