Answer:
4 and 15
Step-by-step explanation:
Let the two numbers be a and b.
The sum of the two is 19. Therefore:
One number (let's use a) is 7 <em>more</em> than twice the other. Thus:
Solve for the system of equations. Substitute the second equation into the first:
Subtract 7 from both sides:
Combine like terms:
Divide by 3:
So, b is 4.
And since they add up to 19, this means that a is:
So our numbers are 4 and 15
And we are done :)
