135 - 5 ( x + 4 ) = 35

5 ( x + 4 ) = 135 - 35 = 100

5 ( x + 4 ) = 100 : 5 = 20

x = 20 - 4

x = 16

135 - 5 ( x + 4 ) = 35

5 ( x + 4 )          = 135 - 35

5 ( x + 4 )          = 100

x + 4                 = 100 : 5

x + 4                 =  20 

x                       = 20 -  4

x                       = 16 

135-5(X+4)=35

Thực hiện phép tính:

\(\left(-17\right)+5+8+17+\left(-3\right)\)

\(=\left[\left(-17\right)+17\right]+\left[5+8+\left(-3\right)\right]\)

\(=0+10\)

\(=10\)

35 : 7 = 5

= 5

\(\left(-\dfrac{1}{2}\right)-\left(-\dfrac{3}{5}\right)+\left(-\dfrac{1}{9}\right)+\dfrac{1}{127}-\dfrac{7}{18}+\dfrac{4}{35}-\left(-\dfrac{2}{7}\right)\)

\(=\left[-\dfrac{1}{2}-\dfrac{1}{9}-\dfrac{7}{18}\right]+\left[\dfrac{3}{5}+\dfrac{4}{35}+\dfrac{2}{7}\right]+\dfrac{1}{127}\)

\(=-\dfrac{18}{18}+\dfrac{35}{35}+\dfrac{1}{127}\)

\(=-1+1+\dfrac{1}{127}\)

\(=\dfrac{1}{127}\)
