Answer 2

Step-by-step explanation:

3x+4y=10-------(1)

2x-2y=2---------(2)

(1)×2=>6x+8y=20

(2)×3=>6x-6y=6

(-) (+) (-)

-------------------------

14y=14

=>y=14/14

=>y=1

Substituting the value of y in equation (1) we get

3x+4y=10

=>3x+4×1=10

=>3x+4=10

=>3x=10-4

=>3x=6

=>x=6/3

=>x=2

so x=2 y=1
