4
Step 1:
subtract 3x from BOTH sides
5
6
Step 2:
subtract 1 from BOTH sides
7
8
Step 3:
divide each side by 2

Step 4:
check the answer x = 2
11
Regardless of which variable term you move first the answer is still x = -14
12
Alternate method:
- Subtract 7x from both sides
- -13 = -10x - 33
- Add 33 to both sides
20 = -10x
- divide both sides by -10 and you still get x = -2
13
Alternate Method:
- Add 6x to both sides
-4x + 15 = 17
- Subtract 15 from both sides
-4x = 2
- Divide both sides by -4 and you still get -0.5 or -1/2
