Question

Solve the following:5x+12=3x+20​

Answer 1

$\sf \bf 5x + 12 = 3x + 20$

On putting the constants and variables separately,

$\sf \bf 5x - 3x = 20 - 12$

On simplifying,

$\sf \bf 2x = 8$

Transposing 2 from LHS to RHS, changing its sign,

$\sf \bf x = \dfrac{8}{2}$

Dividing 8 by 2,

$\sf \bf x = 4.$

So, the value of x = 4.

Verification :-

To check our answer, we just have to put 4 in place of x and see if the LHS = RHS.

Putting x, we get :-

$\sf \bf 5 \times 4 \: + 12 = 3 \: \times 4 + 20$

$\bf 20 + 12 = 12 + 20$

$\bf 32 = 32.$

Since LHS = RHS,

Hence verified! ✔️✔️

Answer 2
