Answer:

The solution is x=2 and y=-1

Step-by-step explanation:

(step 1)

4x + 2y = 6

x - y = 3 - then multiply by 2

4x +2y = 6

2x -2y = 6 then add

6x  x   = 12 x = 12/6 = 2

Substitue back in (step 1)

4 x 2 + 2y = 6

   8 + 2y = 6

Answer is = 2y = -2  y= -1

Solution: x= 2

               y= -1
