câu b là:

=37.(24+76)+63.(79+21)

=37.100+63.100

=100.(37+63)

=100.100

=10000

7/12+5/18+5/36<x<20/13+44/13+27/13

x=2;3;4;5;6

A) \(y=5X-\frac{18.2}{18}=135X-2=13x=3\)

B)\(y=\frac{5x-36}{18}=13\frac{5x}{18}-2=13\frac{5x}{18}=15\frac{x}{18}=3x=54\)

sai bet te be nhe

a, 5x-36:18=13

5x-2=13

x=5-2

x=3

b,(5x-36):18=13

5x-36=13x18

cho mình nhé:):):):):):):)@@@@@@@#######

  (36 x 15 x 169):(5 x 18 x 13)

= (18 x 2 x 3 x 5 x 13 x 13):(5 x 18 x 13)

= 2x3x13x(5 x 18 x 13):(5 x 18 x 13)

= 2 x 3 x 13

= 78

13/36-5/18-x=-11/9

5/18-x=13/36-(-11/9)

5/18-x=19/12

x=5/18-19/12

x= -47/36

vậy x = -47/36

\(\frac{13}{36}-\frac{5}{18}-x=\frac{-11}{9}\)

\(\Leftrightarrow\)\(\frac{13}{36}-\frac{10}{36}-x=\frac{-44}{36}\)

\(\Leftrightarrow\frac{3}{36}-x=\frac{-44}{36}\)

\(\Leftrightarrow x=\frac{3}{36}-\frac{-44}{36}\)

\(\Leftrightarrow x=\frac{47}{36}\)

chắc là vậy

\(\frac{13}{36}\)- \(\frac{5}{18}\)- x = \(\frac{-11}{9}\) 

\(\Leftrightarrow\)13 - 5.2-x=-11 . 4

 \(\Leftrightarrow\)x= -44 -13 +10 

\(\Leftrightarrow\)x= -47

a) 5x – 36 : 18 = 13

5x – 2 = 13

5x = 13+2

5x = 15

x = 15 :5

x = 3

Vậy x = 3
