Answer 1

Answer:

1

Step-by-step explanation:

5x+7y=17 ; 7x+5y=19

(5x+7y)7=17×7 ; (7x+5y)5=19×5

35x+49y=119 ; 35x+25y=95

So on both side there is 35x so it will cut

49y=119 ; 25y=95

Now we will subtract both side.

49y-25y=24

24y=24

y=24/24

y=1

Let's conclude x

5x+7y=17

5x+(7×1)=17

5x+7=17

5x=17-7

5x=10

x=10/5

x=2
