a ) 5*(x+35) =515
=>x+35=515:5
=>x+35=103
=>x=103-35
=>x=68
\(5.\left(x+35\right)=515\)
\(x+35=515:5\)
\(x+35=103\)
\(x=103-35\)
\(x=68\)
5x(x+35)=515
(x+35)=515:5
(x+35)=103
x =103-35
x =68
\(5\left(x+35\right)=515\)
\(\Rightarrow x+35=515:5=103\)
\(\Rightarrow x=103-35=68\)
\(x+35=515:5\)
\(x+35=103\)
\(X=103-35\)
\(x=68\)
k mk nha
5 x (x + 35) = 515
x + 35 = 515 : 5
x = 103 - 35
x = 68
Tìm x :
5 ( x + 35 ) = 515
<=> x + 35 = 515 : 5
<=> x + 35 = 103
<=> x = 103 - 35
<=> x = 68
Vậy x = 68
5 . ( x + 35 ) = 515
( x + 35 ) = 515 : 5
( x + 35 ) = 103
x = 103 - 35
x = 68
vậy x = 68
