Question

Simplifica cada expresion
1. 25-3n+16n
2. 12(x+3y)
3. 5x(-y+9)
4. 4(2x+y)-3(x-5)
5. 3m+2(m-n)-5(m+m)

Answer 1

1. 26n-3n+ 16n = 38n
(25-3+16)n 38n


2. 12(x+3y)= 12x +36y
12x+12x 3y


3. 5x(-y+9)= -5xy +45x
-5xy+5x +9


4. 4(2x+y)-3(x-5) =5x +4y+15
8x+4y-3x+15


5. 3m+2(m-n)-5(m+m)= -5m-2n
3m+2m-2n-5 x 2m
3m+2m-2n-10m
