\(a,255+x=1250\)
\(x=1250-255\)
\(x=995\)
Vậy \(x=995\)
\(b,625-x=245\)
\(x=625-245\)
\(x=380\)
Vậy \(x=380\)
\(a,255+x=1250\)
\(x=1250-255\)
\(x=995\)
\(b,625-x=245\)
\(x=625-245\)
\(x=380\)
a) 255 + x = 1250
x = 1250 - 255
x = 995
b) 625 - x = 245
x = 625 - 245
x = 380
k mình nha ình k lại
a) 225 + x = 1250
x= 1250 - 225
x= 1025
b ) 625 - x = 245
x= 625 - 245
x= 380
Tk mk nha . Thank you so much
