Answer:

x=2/3, y=0

Step-by-step explanation:

3x + 7y = 2,

6x - 5y = 4

Make the x coefficient the same in both equations.

3x + 7y = 2

(whole thing multiplied by 2)

6x + 14y = 4

Now subtract the equations to eliminate the x variable.

 6x + 14y = 4

-(6x - 5y   = 4)

        19y  = 0

           <u>y = 0</u>

Substitute 0 for y in one of the equations.

3x + 7(0) = 2

         3x = 2

           <u>x = 2/3</u>
