X+y=5;x-y=3 solve. ​

Answer»

\large{\underline{\underline{\mathfrak{\green{\sf{QUESTION:-}}}}}}.

  • \:(<klux>X</klux>+y)\:=\:5

And,

  • \:(x-y)\:=\:3

Solve this

\large{\underline{\underline{\mathfrak{\sf{SOLUTION:-}}}}}.

\large{\underline{\mathfrak{\sf{Given\:Equation:-}}}}.

  • \:(x+y)\:=\:5...(1)

  • \:(x-y)\:=\:3.....(2)

\large{\underline{\underline{\mathfrak{\sf{Find\:Here:-}}}}}.

\large{\underline{\underline{\mathfrak{\sf{Explanation:-}}}}}.

[ SUM of these equation ]

\implies\:(2y)\:=\:8

\implies\:y\:=\frac{8}{2}

\implies\boxed{\boxed{\:y\:=\:4}}

Now, keep value of y in (1)

\implies\:(x+4)\:=\:5

\implies\:x\:=\:5-4

\implies\boxed{\boxed{\:x\:=\:1}}

\large{\underline{\underline{\mathfrak{\green{\sf{Answer:-}}}}}}.

  • \:Value\:of\:x\:=\:1

  • \:Value\:of\:y\:=\:4

\large{\underline{\underline{\mathfrak{\green{\sf{Answers:Verification:-}}}}}}.

Keep value of x and y in equation (1)

\implies\:(1+4)\:=\:5

\implies\:5\:=\:5

L.H.S.= R.H.S.

So, we can say that value of x and y are exits this equation .
