1) x - (2x + 1) = 8 – (3x + 3)
2) 15x – 10 = 6x – (x + 2) + (- x + 3)
3) - 2 (x + 1) = – 6
4) - 2 (x – 1) = 4
5) 3 (x – 2) – x = 8
6) 4 (– x – 1) + 5x – 2 = – 2x – x
7) - 2 (– x – 1) = 5 + 1
8) 3 + 2 (4 + 2x) + 1 = 20 – 2 (2 – x)
9) - 2 – x + 4 (– 2x – 3) = – 8x + 1
10) 6 (x – 2 + 3x) = – 3 (– 4x + 1 – 5)
ayudenme por favor
