Question

X+y=5;x-y=3 solve. ​

Answer 1

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

• $\:(x+y)\:=\:5$

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)

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

• Value of x and y

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

[ 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 .

Answer 2

Answer:

HERE IS YOUR ANSWER MATE !!!

Step-by-step explanation:

X + Y = 5 .......(1)

X - Y = 3 ......(2)

By using elimination method

X + Y = 5

X - Y = 3

Therefore,

2X = 8

X = 4

Put the value of X in equation 1

X + Y = 3

4 + Y = 3

Y = 4 + 3

Y = 7
