Question

CAN YOU TELL TO ME HOW 9 + 5 = 2 ? MY MISS HAS ASKED THIS ANSWER AND I DONT UNDERSTAND THIS ANSWER

Answer 1

$\boxed {\underline {\mathbb {GIVEN:-}}}$

9 + 5 = 2

$\boxed {\underline {\mathbb {TO\:FIND:-}}}$

to prove 9 + 5 = 2

$\boxed {\underline {\mathbb {SOLUTION:-}}}$

it's obvious that

$9+5 \neq 2$

[also i guess your ma'am has played with your mind or she also don't know variable properly (just joking);]

so lets modify the equation the and equation will be $\boxed {9+5=2+x}$

let's the number to be added be x so that $L.H.S.=R.H.S.$

by soling the new equation we get

$9+5=2+x$

$14=2+x$ [ ← added 9+5 which is on L.H.S. that gives 14 ]

$14-2=x$ [ ← bringing 2 from R.H.S. to L.H.S. so it get -2 ]

$x=12$

now,

putting value in equation we get

$9+5=2+x$

$9+5=2+14$ [ ← putted value in equation ]

$\boxed {14=14}$

hence $LHS=RHS$

⇔ ⇔ ⇔ ⇔ ⇔ ⇔ ⇔ ⇔ ⇔ ⇔ ⇔ ⇔ ⇔ ⇔ ⇔ ⇔ ⇔ ⇔ ⇔ ⇔ ⇔ ⇔ ⇔ ⇔

Note:-

your ma'am had either tricked you out or she forgotten variable adding in your question  

if i had to solve 9 + 5 = 2

than it would we $14=2$ ⇒ $0=2-14$ ⇒ $0=-12$ or $12=0$
