Question

The second of two numbers is 5 more than twice the first. their sum is 80. find the numbers

Answer 1

Explanation:

x = first number, y = second number

x + y = 80

y = 2x + 5

x + 2x + 5 = 80

3x + 5 = 80

3x = 80 - 5

3x = 75

x = 75/3

x = 25

y = 2x + 5

y = 2(25) + 5

y = 50 + 5

y = 55

so ur numbers are : 25 and 55 <==
