Answer:
x = -6
Step-by-step explanation:
3x + 7 = 2x + 1
Subtract 7 on both sides to leave 3x alone
3x = 2x - 6
Subtract 2x on both sides to have X on one side only
3x - 2x = x
x = -6
I'm not entirely sure as to what Dcmam is but there is really not much else you can do to find this value of x, it's as simple as that.
