bạn nào làm hộ mình với mình tích cho

x - 1 = 0 : 12
x - 1 = 0
x = 0 + 1
x = 1
b) ( 6x - 39 ) : 3 = 201
6x - 39 = 201 . 3
6x - 39 = 603

tk nha ^^
1. Tim so tu nhien x, biết :
a) (6x - 39) : 3 =201
b) 23 + 3x = 56 : 53
c) 541 + (218 - x) = 735
d) 5(x + 35) = 515
\(\left(6x-39\right)\div3=201\)
\(6x-39=201.3\)
\(6x-39=603\)
\(6x=603+39=642\)
\(\Rightarrow x=642\div6=107\)
\(23+3x=5^6\div5^3\)
\(23+3x=5^{6-3}\)
\(23+3x=5^3=125\)
\(3x=125-23\)
\(3x=102\)
\(\Rightarrow x=34\)
\(541+\left(218-x\right)=735\)
\(218-x=735-541\)
\(218-x=194\)
\(x=218-194\)
\(x=24\)
\(5\left(x+35\right)=515\)
\(x+35=515\div5\)
\(x+35=103\)
\(x=103-35\)
\(x=68\)

chắc là đúng. Bạn nên thử lại
Dễ mà :
