Question

the sum of two no. is 84 and one of them is 10 more than the other , if one of them is x , the find the no​

Answer 1

Answer :-

• The numbers are 37 and 47.

To find :-

• The numbers.

Step-by-step explanation :-

One of the numbers is "x".

It is given that :-

• The other number is 10 more than the first one.

Therefore :-

• The other number will be "x + 10".

Now,

• The sum of these two numbers is 84.

Which means :-

• That the sum of x and x + 10 is 84.

-----------------------------------------------------------

Hence,

$\longmapsto \bf x + x + 10 = 84$

$\bf \longmapsto 2x + 10 = 84$

$\bf \longmapsto 2x = 84 - 10$

$\longmapsto \bf 2x = 74$

$\bf\longmapsto x = \dfrac{74}{2}$

$\longmapsto \overline{ \boxed{\bf x = 37}}$

Thus, the numbers are :-

$\sf x = 37.$

$\sf x + 10 = 37 + 10 = 47.$

What is an equation?

• An (algebraic) equation is a statement that two expressions are equal. It may involve one or more than one variables.

An equation has two sides separated by the '=' sign. The side on the left of equal sign is called left hand side (LHS) and the side on the right of equal sign is called right hand side (RHS).
