Answer 2

$\huge\bold{\mathbb{QUESTION}}$

Solve the following equation:

$7x-5=2x$

$\huge\bold{\mathbb{TO\: FIND}}$

The value of $x.$

$\huge\bold{\mathbb{SOLUTION}}$

$7x-5=2x$

Combine the like terms.

$\implies -5=2x-7x$

$\implies -5=-5x$

$\implies {\dfrac{-5}{-5}}=x$

$\implies \cancel{{\dfrac{-5}{-5}}}=x$

$\implies 1=x$

$\huge\bold{\mathbb{HENCE}}$

$x=1$

$\huge\bold{\mathbb{THEREFORE}}$

The value of $x$ is $1.$

$\huge\bold{\mathbb{NOT\:SURE\:??}}$

$\huge\bold{\mathbb{VERIFICATION}}$

$7x-5=2x$

Putting $x=1,$

$\implies (7\times 1)-5=(2\times1)$

$\implies 7-5=2$

$\implies 2=2$

So, $L.H.S = R.H.S.$

Hence, verified ✓ .
