Answer 2

Answer -

• The number is 15.

To find -

• The number.

Step-by-step explanation -

Let the number be "x".

Multiplying the number by 4 -

• We get "4x".

According to the Question -

• 4x = x + 45.

Solving the Equation -

$\longmapsto\rm 4x = x + 45$

$\longmapsto \rm 4x - x = 45$

$\longmapsto \rm 3x = 45$

$\longmapsto \rm x = \cancel{\dfrac{45}{3}}$

$\longmapsto \rm x = 15$

Thus -

• The number is 15.

________________________________

V E R I F I C A T I O N -

• To check our answer, let's substitute the value of "x" in the equation and see whether LHS = RHS.

LHS :

$\hookrightarrow 4x$

$\hookrightarrow 4 \times 15$

$\hookrightarrow 60$

RHS :

$\hookrightarrow x + 45$

$\hookrightarrow 15 + 45$

$\hookrightarrow 60$

LHS = RHS.

Hence verified!!
