Answer:
3x + 1 – 2x = 9 – 3
Explanation:
3) 6 + 2x – 4 = x – 1
4) – 6 – 2x = - 3x – 6
5) x + x +4 +2 = 8
6) 2x + x +5 – 5 = 6
7) 2x – x – 3 – 5 = 2
8) 2x + 2 – 1 – x = 2
9) 5x – 4= 3x – 2
10) 2x – 5 +1 +x = + x – 6
11) – 2x – 5 = 6 – x – 2x
12) – 10 – 4 x + 2x = – 3 – 4x
13) – 5x – 6 + 4 = 4 + 2x – 8x
14) – x = – 6 – 2 – 2x
15) 5x – 10 – 3x +3 + 2x = 20 – x – 4 – 3 + 3x
