Sagot :

SOLUTION

Let the smaller number be x

Let the larger number be y

Since the larger number is 31 more than 5 times the smaller number, it folllows:

[tex]y=5x+31[/tex]

The sum of the two integers is 463, it follows

[tex]x+y=463[/tex]

Substitute y=5x+31 into the equation

[tex]x+5x+31=463[/tex]

Solve for x

[tex]\begin{gathered} 6x=463-31 \\ 6x=432 \\ x=\frac{432}{6} \\ x=72 \end{gathered}[/tex]

Substitute x=72 into y=5x+31

[tex]\begin{gathered} y=5\left(72\right)+31 \\ y=360+31 \\ y=391 \end{gathered}[/tex]

Therefore the two integers are 72 and 391
