Answer:
The numbers are 4 and 11.
Step-by-step explanation:
If one number is 7 more than the other, you can express that as x+7 is equal to the other number which we can call "y".
If you add "y" which is basically x+7 to x, which is one of the numbers, your equation will be x+x+7=15.
Simplify: 2x+7=15.
Subtract 7 from both sides of the equation and you have 2x=8.
Divide by 2 on both sides and x is equal to 4.
You plug 4 back into the expression "x+7".
4 plus 7 is 11.
