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
