Question

factorizacion resuelva según su según corresponda 2 + 5 + 8​

Answer 1

1) 2+5+8=15

2) (a-2)/4 + 5 + a/2 = 15

(a-2) + 20 + 2a = 60

3a + 18 = 60

3a = 42

a = 42/3

a = 14

3) (2b)/5 + 5 + (b+2)/2 = 15

2(2b) + 50 + 5(b+2) = 150

4b + 50 + 5b + 10 = 150

9b + 60 = 150

9b = 150 - 60

9b = 90

b = 10

4) x/3 + 5 + 3x = 15

x + 3(5) + 3(3x) = 3(15)

x + 15 + 9x = 75

10x = 75 - 15

10x = 60

x = 60/10

x = 6
