One integer added to another integer gives a sum of 2. When the larger integer is subtracted from the smaller integer, the difference is -14. What could the two integers be? Explain.

Respuesta :

For this case we have the following variables, let:

x: The greater integer

y: The minor integer

We have to:

[tex]x + y = 2 (1)\\y-x = -14 (2)[/tex]

Thus, we have a system of two equations with two unknowns. To solve, we follow the steps below:

Step 1:

We add both equations:

[tex]x + y + y-x = 2-14\\2y = -12[/tex]

[tex]y = \frac {-12} {2}\\y = -6[/tex]

Thus, the smallest integer is [tex]y = -6[/tex]

Step 2:

We substitute "y" in any of the equations and clear x:

[tex]x + y = 2\\x + (- 6) = 2\\x-6 = 2\\x = 2 + 6\\x = 8[/tex]

Thus, the largest integer is [tex]x = 8[/tex]

So:

[tex]8 + (- 6) = 8-6 = 2\\-6-8 = -14[/tex]

Anwer:

Integer minor, [tex]y = -6[/tex]

Integer greater,[tex]x = 8[/tex]
