Question

Determine em u=q a/7- a+1/4 = a+1/6
m- m/3 -m+1/2=3-m-2/2

Answer 1

Olá Pacienc

a/7 - (a + 1)/4 = (a + 1)/6 

mmc(4,6,7) = 84

12a - 21a - 21 = 14a + 14 

12a - 21a - 14a = 14 + 21

-23a = 35 

a = -35/23 

m - m/3 - (m + 1)/2 = 3 - (m - 2)/2

mmc(2,3) = 6

6m - 2m - 3m - 3 = 18 - 3m + 6

6m - 2m = 18 + 6 + 3

4m = 27

m = 27/4
