2. 2a - 6a - 2a + 1a=

3. 3ab - 4ac + 3ac=

4. 5 × - 2y + 3z - 1z + 5y - 2× =

5. -(2m - 3n) + 4m - 2n=​

Answer 1

Explicación paso a paso:

1. 2m - 3m + 5m = 4m

2. 2a - 6a - 2a + 1a = -5a

3. 3ab - 4ac + 3ac = 3ab-ac= 3bc

4. 5x (-2y) + 3z -1z +5y - 2x = 3x +3y +2z

5. -(2m-3n) + 4m - 2n= -2m -3n + 4m - 2n = 2m - 5n
