Trả lời
7x - 8 = 713
7x = 721
x = 103
( 6x - 39 ) : 3 = 201
6x - 39 = 603
6x = 642
x = 107
Study well
7x - 8 = 713 (6x - 39) / 3 = 201
7x = 713 + 8 6x - 39 = 201 * 3
7x = 721 6x - 39 = 603
x = 721 / 7 6x = 603 + 39
x = 103 6x = 642
x = 642 / 6
x = 107
\(7x-8=713\)
\(7x=713+8\)
\(7x=721\)
\(x=721:7\)
\(x=103\)
Vậy \(x=103\)
b) \(\left(6x-39\right):3=201\)
\(\left(6x-39\right)=201.3\)
\(6x-39=603\)
\(6x=603+39\)
\(6x=642\)
\(x=642:6\)
\(x=107\)
Vậy \(x=107\)
Chúc bạn học tốt !!!
\(7x-8=713\)
\(7x=713+8\)
\(7x=211\)
\(x=72:17\)
\(x=103\)
\(7x-8=713\Rightarrow7x=713+8=721\)
\(x=721:7=103\)Vậy \(x=103\)
\(\left(6x-39\right):3=201\Rightarrow6x-39=201\times3=603\)
\(\Rightarrow6x=603+39=642\Rightarrow x=642:6=107\)
bạn làm theo cách này nhé
7x - 8 = 713 ( 6x - 39 ) : 3 = 201
7x = 713 + 8 ( 6x - 39 ) = 201* 3
7x = 720 ( 6x -39 ) = 603
x = 720 : 7 6x = 603+ 39
x = 90 6x = 642
x = 642 : 6
x = 107
Chúc bạn làm bài tốt nhé
ko ghi lại đề
7x = 713 + 8
7x= 721
x=721:7
x=103
(6X - 39) = 201.3
6x - 39 = 603
6x = 603 + 39
6x = 642
x=642 : 6
x= 107
\(\left(6x-39\right):3=201\)
\(6x-39=201\times3\)
\(6x-39=603\)
\(6x=603+39\)
\(6x=642\)
\(x=642:6\)
\(x=107\)
