Answer: (1, 1)

Step-by-step explanation:

Keep 6x + 3y = 3 how it is and multiply 3 to the next equation.

-2x + 4y = -6

-6x + 12y = -18

Now add the equations:

-6x + 12y = -18

6x + 3y = 3

15y = -15

Solve for y by dividing:

15y = -15

y = -1

Since we got y, substitute -1 into the first equation:

6x + 3y = 3

6x + 3 (-1) = 3

Now just solve for x by adding 3 to both sides:

6x + -3 + 3 = 3 + 3

6x = 6

Now divide 6 by both sides:

6x/6 6/6

X = 1
