a) 936 + ( 49 : x ) = 943
49 : x = 943 - 936
49 : x = 7
x = 49 : 7
x = 7
b) 26 + ( x . 12 ) = 98
x . 12 = 98 - 26
x . 12 = 72
x = 72 : 12
x = 6
a) 936 + (49:x)=943 b) 26 + (X x 12 )=98
=>49:x=943-936=7 =>X x 12 =72
=>x=49:7 =>X=72:12=6
x=7
936 + (49 : x) = 943
49 : x = 943 - 936
49 : x = 7
x = 49 : 7
x = 7
\(26+\left(x\times12\right)=98\)
\(x\times12=98-26\)
\(x\times12=72\)
\(x=72:12\)
\(x=6\)
a)936+(49:x)=943
=>(49:x)=943
=>(49:x)=943-936
=>49:x=7
=>x=49:7
=>x=7
b)24+(x.12)=98
=>(x.12)=98-24
=>(x.12)=74
=>x=74:12
=>x=37/6
a) \(936+\frac{49}{x}=943\)
\(=>\frac{49}{x}=943-936=7\)
\(=>x=\frac{49}{7}=7\)
=>\(x=7\)
Vậy \(x=7\)
b)\(26+\left(x.12\right)=98\)
\(=>12.x=98-26=72\)
\(=>x=\frac{72}{12}=6\)
Vậy \(x=6\)
