this will be a bit tricky in that that we have 3 equations to solve.
equation #1:
x+3 = 2x+1
step 1 - subtract x and subtract 1 to get
2 = x
-----
equation #2:
x+3 = -(2x+1)
step 1 - distribute the - through to get
x+3 = -2x -1
step 2 - add 2x and subtract 3 to get
3x = -4
step 3 - divide to get
x = -4/3
-----
equation #3:
2x+1 = -(x+3)
step 1 - distribute the - through to get
2x + 1 = -x -3
step 2 - add x and subtract 1 to get
3x = -4
step 3 - divide to get
x = -4/3
----
so it appears that our answers are
x = -4/3, 2
