Correct Question-:

  • 18 is taken away from 8 times of a number is 30. Find the number.

AnswEr-:

  • \underline{\boxed{\star{\sf{\blue{The\:number\:is\:=\frak{6}.}}}}}

EXPLANATION-:

  •  \frak{Given \:\: -:} \begin{cases} \sf{18\: is \:taken \:away\: from \:8\: times \:of \:a \:number\: is\: 30. }\end{cases} \\\\

  •  \frak{To \:Find\: -:} \begin{cases} \sf{The\:number. }\end{cases} \\\\

Solution-:

  •  \frak{Let's \:Assume \: -:} \begin{cases} \sf{The\:number\:be\:x.}\end{cases} \\\\

  •  \frak{By\:Understanding\:Concept \:\: -:} \begin{cases} \sf{18\: is \:taken \:away\: from \:8\: times \:of \:a \:number\: is\: 30.} & \\\\\sf{Then,}& \\\\ \sf{Formed \:Equation = \frak{8 × x - 18 =30}}\end{cases} \\\\

Then,

  • Solving for x -:

  • \implies{\sf{\large {8× x - 18 =  30}}}
  • \implies{\sf{\large {8x - 18 =  30}}}
  • \implies{\sf{\large {8 x =  30+18}}}
  • \implies{\sf{\large {8x =  48}}}
  • \implies{\sf{\large {x =  \frac{48}{8}}}}
  • \implies{\sf{\large {x =  6}}}

Therefore,

  • \underline{\boxed{\star{\sf{\blue{x = 6.}}}}}

Now ,

  •  \frak{Putting \:x =6 \: -:} \begin{cases} \sf{The\:number\:is\:x=\frak{6}}\end{cases} \\\\

Hence ,

  • \underline{\boxed{\star{\sf{\blue{The\:number\:is\:=\frak{6}.}}}}}

Verification

  •  \frak{Given \:\: -:} \begin{cases} \sf{18\: is \:taken \:away\: from \:8\: times \:of \:a \:number\: is\: 30.} & \\\\\sf{Then,}& \\\\ \sf{Formed \:Equation = \frak{8 × x - 18 =30}}\end{cases} \\\\

  • \implies{\sf{\large {Equation \: 1 = 8 × x   - 18 =  30}}}

  • Here,
  • \implies{\sf{\large {x =  6}}}

Now ,

  • \implies{\sf{\large {8× 6 - 18 =  30}}}
  • \implies{\sf{\large {48 - 18 =  30}}}
  • \implies{\sf{\large {30 =  30}}}

Therefore,

  • \implies{\sf{\large {LHS =  RHS}}}

  • \underline{\boxed{\star{\sf{\blue{Hence,\: Verified.}}}}}
