Question

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

Answer 1

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

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
