Question

dati nr 2 factor comun:
2a+2b
2n+2
14-10a
2x+2y
2+2k
30x-2
2b-2c
4a+6b

Answer 1

2 a + 2 b = 2 × ( a + b )

2 n + 2 = 2 × ( n + 1 )

14 - 10 a = 2 × ( 7 - 5 a )

2 x + 2 y = 2 × ( x + y )

2 + 2 k = 2 × ( 1 + k )

30 x - 2 = 2 × ( 15 x - 1 )

2 b - 2 c = 2 × ( b - c )

4 a + 6 b = 2 × ( 2 a + 3 b )
