Question

find the solución to the System of equations x+3y=7 and 2x+4y=8​

Answer 1

Answer:

The answer to your question is: x = -2 y = 3

Step-by-step explanation:

         x + 3y = 7          (1)

       2x + 4y = 8          (2)

Multiply (1) by -2

     

         -2x - 6y = -14

          2x + 4y = 8

          0    -2y = -6

              y = -6/-2

               y = 3

 x + 3(3) = 7

 x + 9 = 7

 x = 7 - 9

 x = -2
