Y = 6x + 14
2x - y = 2
so
2x - (6x + 14) = 2
2x -6x - 14 = 2
-4x - 14 = 2
-4x = 2+14
-4x = 16
x = -4
y = 6(-4) + 14
y = -24 + 14
y = -10
(x,y) = (-4,-10)

Step-by-step explanation:
So, im doing it in fractions
First we have to convert:
4.2= 4 2/10= 4 1/5
0.14=14/100
Then make fractions( if needed)
21/5÷14/100
21/5x100/24=2100/70=210/7=30
