The sum of two numbers is 75. The second number is<br> less than twice the first. Find the numbers.
Lera25 [3.4K]

Answer:

First number =26

Second number =49

Step-by-step explanation:

Question:

The sum of two numbers is 75. The second number is 3 less than twice the first. Find the numbers.

Given:

Sum of two numbers = 75

The second number is 3 less than twice the first.

To find the numbers.

Solution:

Let the first number be = x

Let second number be = y

The sum equation can be given as:

x+y=75

It is given that the second number is 3 less than twice the first.

This can be given as:

y=2x-3

Substituting the value of y in terms of x in the sum equation.

x+(2x-3)=75

Combining like terms.

3x-3=75

Adding 3 both sides.

3x-3+3=75+3

3x=78

Dividing both ides by 3.

\frac{3x}{3}=\frac{78}{3}

x=26

Substitution x=26 in the second equation to find y.

y=2(26)-3\\y=52-3\\\therefore y=49

Thus, first number =26 and second number =49.
