Question

One number is 3 less than another number. If the sum of the two numbers is 177, find each number.

Answer 1

Answer:

first no. = 87

second no. = 90(87+3)

Step-by-step explanation:

first no.= x

second no.= 3+x

sum of the two no.s= 177

=> x + 3+ x = 177

=> 2x = 177 - 3

=> 2x = 174

=> x = 87

Answer 2

Given,

One number is 3 less than another number.

To Find,

If the sum of the two numbers is 177, find each number.

Solution,

We can solve the question as follows:

It is given to us that one number if 3 less than another number and the sum of the two numbers is 177.

Let the first number be x and the other number be y. Assuming x to be the smaller among the two,

$x = y - 3$   -------- (1)

$x + y = 177$  -------- (2)

Substituting equation (1) in equation (2),

$y - 3 + y = 177$

$2y = 177 + 3$

$2y = 180$

$y = 90$

And,

$x = y - 3 = 90 - 3 = 87$

Hence, the two numbers are 87 and 90.
