Question

x=-35/10 +33/12 e y=-17/12 calcule -x+y

Answer 1

Resposta:

x=-3/4 e y=-17/12

-x+y =-1/3

Explicação passo-a-passo:

x=-35/10

MMC

10,12|2

5,6|2

5,3|5

1,3|3

1,1| 2*2*5*3=60

$x=\frac{-35*6}{60} +\frac{33*5}{60} = \frac{-210+165}{60} =\frac{-45}{60} =\frac{-3}{4}$

y=-17/12

MMC

12,4|2

6,2|2

3,1|3

1,1| 2*2*3 = 12

$-x+y=-\frac{-3}{4}+\frac{-17}{12} =\frac{3*3-17}{12} = \frac{9-17}{12}=\frac{-8}{12} =\frac{-1}{3}$
