Question

The product of two integers is 72. One number is two less than five times the other.

Answer 1

Other number: x
one number: 5x - 2

x (5x - 2)=72
5x^2 - 2x = 72

Answer 2

Answer:

$5x^{2}-2x=72$

Step-by-step explanation:

Let

y------> one integer number

x----> the other integer number

we know that

$xy=72$ ----> equation A

$y=5x-2$ -----> equation B

substitute equation B in equation A

$x(5x-2)=72$

$5x^{2}-2x=72$
