Answer 2

Answer :-

• The correct option is a)
• 5 satisfies the given equation.

Step-by-step explanation :-

$\bf 3m = 15$

Transposing 3 from LHS to RHS, changing its sign,

$\bf m = \dfrac{15}{3}$

Dividing 15 by 3,

$\bf m = 5.$

So, the value of m = 3.

Therefore, the correct option is a) 5.

Verification :-

To check our answer, we just have to put 5 (The value of m) in place of m and see if the LHS = RHS.

Putting 5 in place of m,

$\bf 5 \times 3 = 15$

Multiplying 5 and 3,

$\bf 15 = 15.$

Since LHS = RHS,

Hence verified! ✔️✔️

What is an equation?

In Maths, an equation is a statement which says that two expressions are equal. They are connected with = sign. An equation is incomplete if it does not contain the = sign.

Some examples :-

$\bf 2x + 5 = 15.$

$\bf \dfrac{5x}{10} = 20.$

$\bf 9 + x = 28.$

$\bf 2 \:(5x + 9) = 5 - x$
