упростите выражение: 13b+19b; 44d-37d; 34n+n; 127q-q; 36y-19y+23y; 49a+21a+30.
13b+19b=b*(13+19)=32b
44d-37d=d*(44-37)=7d
34n+n=n*(34+1)=35n
127q-q=q*(127-1) =126q
36y-19y+23y=y(36-19+23) =40y
49a+21a+30a=a*(49+21+30)=100a , если а недописано
49a+21a+30=а*(49+21) +30=70а+30
13b + 19b = b(13+19) = 32b
44d - 37d = d(44-37) = 7d
34n + n = n(34+1) = 35n
127q - q = q(127-1) = 126q
36y - 19y + 23y = y(36-19+23) = 40y
49a + 21a + 30 = a(49+21) + 30 = 70a+30
