6+66*t 30*x-24

Answer 1

6a+6b = 6×(a+b)
6x+6y = 6×(x+y)
6d-6f = 6×(d-f)
6×35+6×56 = 6×(35+56) = 6×91
816×6-815×6 = 6×(816-815) = 6×1 = 6
6×123+6 = 6×(123+1) = 6×124 = 744
6m+6 = 6×(m+1)
6+6k = 6×(1+k)
6a+12b = 6×(a+2b)
30a-12b = 6×(5a-2b)
6m-18 = 6×(m-3)
6a+6b+6c = 6×(a+b+c)
6+66t = 6 (1+11t)
30x-24 = 6×(5x-4)
