Answer:
1 NUMBER 39 SECOND NUMBER 40
Step-by-step explanation:
Take half of 79 and get 39.5 then
the answers are the two whole numbers
on each side of 39.5, which are 39 and 40.
Here's the way your teacher wants you to do it:
First integer = x
Next integer = x+1
Add them together with a plus sign and then write an = sign and 79:
x + x+1 = 79
Combine like terms
2x+1 = 79
Subtract 1 from both sides:
2x = 78
Divide both sides by 2:
x = 39
First integer = x = 39
Next integer = x+1 = 39+1 = 40
