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 = [tex]x[/tex]

Let second number be = [tex]y[/tex]

The sum equation can be given as:

[tex]x+y=75[/tex]

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

This can be given as:

[tex]y=2x-3[/tex]

Substituting the value of [tex]y[/tex] in terms of [tex]x[/tex] in the sum equation.

[tex]x+(2x-3)=75[/tex]

Combining like terms.

[tex]3x-3=75[/tex]

Adding 3 both sides.

[tex]3x-3+3=75+3[/tex]

[tex]3x=78[/tex]

Dividing both ides by 3.

[tex]\frac{3x}{3}=\frac{78}{3}[/tex]

[tex]x=26[/tex]

Substitution [tex]x=26[/tex] in the second equation to find [tex]y[/tex].

[tex]y=2(26)-3\\y=52-3\\\therefore y=49[/tex]

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