Answer:

x=2

y=0

Step-by-step explanation:

5x+7y=10;

3x-14y=6

Multiply the first equation by 2

2(5x+7y) =10*2

10x +14y = 20

Add this to the second equation to eliminate y

10x +14y = 20

3x-14y=6

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

13x +0y = 26

13x = 26

Divide each side by 13

13x/13 = 26/13

x=2

Now we find y

3x-14y = 6

3(2) -14y = 6

6 - 14y = 6

Subtract 6 from each side

6-6-14y = 6-6

-14y=0

y=0
