Answer:

(0,3)

Explanation:

To solve the system of equations:

2x + 4y = 12

3x + y = 3

We can use the substitution method or the elimination method. Let's use the elimination method to solve this system.

To eliminate the y term, we'll multiply equation 2) by 4:

4(3x + y) = 4(3)

12x + 4y = 12

Now we have the system of equations:

2x + 4y = 12

12x + 4y = 12

Subtract equation 1) from equation 3) to eliminate the y term:

(12x + 4y) - (2x + 4y) = 12 - 12

12x + 4y - 2x - 4y = 0

10x = 0

x = 0

Now substitute x = 0 into equation 2) to find y:

3(0) + y = 3

y = 3

Therefore, the solution to the system of equations is x = 0 and y = 3.

To check the solution, we can substitute x = 0 and y = 3 into the original equations:

2(0) + 4(3) = 12

0 + 12 = 12 (True)

3(0) + 3 = 3

0 + 3 = 3 (True)

So, the solution (0, 3) satisfies both equations.
