I think I already answered it to you from the same question you asked earlier.
But anyways, the answer is in the image below and the steps are also in one of the images too.
Hope this helps! :)
The answer is 15/8 because it just is you know the vibes
X = 2y - 12....so sub 2y - 12 in for x in the other equation
3x + 4y = 14
3(2y - 12) + 4y = 14
6y - 36 + 4y = 14
6y + 4y = 14 + 36
10y = 50
y = 50/10
y = 5
x = 2y - 12
x = 2(5) - 12
x = 10 - 12
x = -2
solution is (-2,5) <==
