What mistake was made in solving the following system of equations given?

y = 3x – 4

y = 5x + 2

Step 1- 3x – 4 = 5x + 2
Step 2- -4 = 2x + 2
step 3- −2 = 2x
step 4- −1 = x
A-Should have added 3x to both sides in Step 1
B-Should have divided by -2 in Step 3
C-Subtracted incorrectly from Step 2 to Step 3
D-Should not have solved for y
