\(413-5\left(x-5\right)=128\)
\(5\left(x-5\right)=413-128\)
\(5\left(x-5\right)=285\)
\(x-5=285:5\)
\(x-5=57\)
\(x=57+5\)
\(x=62\)
Vậy...
413 - 5 . ( x - 5 ) = 128
5 . ( x - 5 ) = 413 - 128
5 . ( x - 5 ) = 285
x - 5 = 285 : 5
x - 5 = 57
x = 57 + 5
x = 62
Vậy x = 62
413-5.(x-5)=128
5.(x-5)=413- 128
5.( x -5 ) =285
x -5 = 285: 5
x-5 = 57
x = 57+5
x = 62 thuộc N
Vậy x =62
\(413-5.\left(x-5\right)=128\)
\(5.\left(x-5\right)=413-128\)
\(5.\left(x-5\right)=285\)
\(x-5=285:5\)
\(x-5=57\)
\(x=5+57\)
\(x=62\)
Học tốt nha !!!
413-5.(x-5)=128
5.x-5 =413-128
5.x-5 =285
x-5 =285:5
x-5 = 57
x = 57+5
x = 62
