Correct Question-:

  • Solve the linear equation-:

  • \implies {\bigstar {\sf{\large {Equation\:=\:7+4x = 9x -13  }}}}\\\\

AnswEr-:

  • \blue{\underline{\boxed{\implies {\sf{The\:value \:of\: x = 4 }}}}}

\implies {\bigstar {\sf{\large {Explanation-: }}}}\\\\

  •  \mathrm{Given \:\: -:} \begin{cases} \sf{Equation\:=\: 7 +4x = 9x-13}\end{cases} \\\\

  •  \mathrm{To \:Find\: -:} \begin{cases} \sf{Solve\:the\:linear\:Equation. }\end{cases} \\\\

\dag {\underline {\sf{\large { Solution\:of\:Question\:-: }}}}\\\\

  • \star {\bigstar {\sf{\large { Now , \: Solving\:for\:x\:in\:Equation-: }}}}\\\\

  • \implies {\sf{Equation\:=\: 7 +4x = 9x-13}}

  • \star {\bigstar {\sf{\large { Now -: }}}}\\\\

  • \implies {\sf{\: 7 +4x = 9x-13}}

  • \implies {\sf{\: 7 +13+4x = 9x}}

  • \implies {\sf{\: 7 +13 = 9x-4x}}

  • \dag {\bigstar {\sf{\large { Or , }}}}\\\\

  • \implies {\sf{\: 9x-4x = 7+13}}

  • \implies {\sf{\: 5x = 7+13}}

  • \implies {\sf{\: 5x = 20}}

  • \implies {\sf{\: x = \dfrac{20}{5}}}

  • \implies {\sf{\: x = 4 }}

\implies {\bigstar {\sf{\large {Hence,  }}}}\\\\

  • \blue{\underline{\boxed{\implies {\sf{The\:value \:of\: x = 4 }}}}}

__________________________________________

  • \implies {\bigstar {\sf{\huge {♡Verification \:-: }}}}\\\\

  • \implies {\bigstar {\sf{\large {Equation\:=\:7+4x = 9x -13  }}}}\\\\

\implies {\bigstar {\sf{\large {Here,  }}}}\\\\

  • \implies {\sf{\: x = 4 }}

\implies {\bigstar {\sf{\large {Now,\:Putting \:known\:values \:=}}}}\\\\

  • \implies {\sf{\: 7 +4\times 4 = 9 \times 4 -13}}

  • \implies {\sf{\: 7 + 16 = 36 -13}}

  • \implies {\sf{\: 23 = 23}}

Therefore-:

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

  • \implies {\bigstar {\sf{\large {Hence, \:\:Verified  }}}}\\\\
