Question

Tìm x

2*(x+3=1650)

(76-x):3=13

giúp mk vs nha mk đg cần gấp

Answer 1

\(2\cdot\left(x+3\right)=1650\)

\(\Leftrightarrow x+3=1650:2\)

\(\Leftrightarrow x+3=825\)

\(\Leftrightarrow x=822\)

  

\(\left(76-x\right):3=13\)

\(\Leftrightarrow76-x=39\)

\(\Leftrightarrow x=37\)

Answer 2

Câu 1 :1650:2-3=822

Câu 2:76-(13*3)=37

Answer 3

2 x (x+3) = 1650

       x+3  = 1650 : 2

       x+3  = 825

           x  = 825-3

           x  = 822

Answer 4

2.(x+3)=1650

x+3=1650:2

x+3=845

x=825-3

x=822

(76-x):3=13

76-x=13x3

76-x=39

     x=76-39

     x=37

Answer 5

\(2\)\(\left(x+3\right)\)\(=1650\)

\(\Leftrightarrow x+3=1650:2\)

\(\Leftrightarrow x+3=825\)

\(\Leftrightarrow x=822\)
