Answer 2

Answer:

X = 1/5

Y = 11/10

Step-by-step explanation:

3x + 4y = 5

2x + 6y = 7

Multillying first equation with 2 and second equation with 3

So we get,

6x + 8y = 10

6x + 18y = 21

(-)  (-)        (-)

= -10y = -11

y = 11/10

x = 7 - 6y/2

x = 7 - 6×11/10/2

x = 7 - 66/20

Therefore x = 1/5
