X x 62 +X x 48 = 4200
=> X x (62+48)=4200
=> X x 110=4200
=> X=4200:110
=> X=\(\frac{420}{11}\)
Xx62+Xx48 = 4200
Xx(62+48)=4200
Xx110=4200
X=4200:110
X=38(18)
X×62+X×48=4200
X×(62+48)=4200
X×110=4200
X =4200:110
X=\(\frac{420}{11}\)
Xx62+Xx48 = 4200
<=> Xx(62+48) = 4200
<=> Xx110 = 4200
<=> X = 4200 : 110
<=> X = 420/11
\(Xx62+Xx48=4200\)
\(Xx\left(62+48\right)=4200\)
\(Xx110=4200\)
\(X=4200:110\)
\(X=\frac{4200}{110}\)( Phép này bị dư bạn ạ )
\(x\times62+x\times48=4200\)
\(\Rightarrow x\times\left(62+48\right)=4200\)
\(\Rightarrow x\times110=4200\)
\(\Rightarrow x=\frac{420}{11}\)
x * 62 + x * 48 = 4200
x * ( 62 + 48 ) = 4200
x * 110 = 4200
x = 4200 : 110
x = \(\frac{420}{11}\)
Chúc bạn học tốt!
X x 62 + X x 48 = 4200
X x ( 62 + 48 ) = 4200
X x 110 = 4200
X = 4200 : 110
X =\(\frac{420}{11}\)
