Answer 1

x = 6

y = - 4

Explanation:

3x + 4y = 2

2x + 2y = 4

Time the second equation by -2

3x + 4y = 2

-4x - 4y = - 8

-x = -6

x = 6

Now we put 6 in for x and solve for y

3(6) + 4y = 2

18 + 4y = 2

4y = -16

y = - 4

Let's Check

3(6) + 4(-4) = 2

18 - 16 = 2

2 = 2

So, x = 6 and y = -4 is the correct answer.
