Answer:
One of the numbers is 5
The other number is 17
Step-by-step explanation:
You could do this just by guessing numbers. But I think you are intended to do it with algebra.
x + y = 22
y = 2*x + 7 Substitute the y value in this equation into the first equation
x + 2x + 7 = 22 Combine the xs on the left.
3x + 7 = 22 Subtract 7 from both sides.
3x+7-7=22- 7 Combine
3x = 15 Divide by 3
3x/3 = 15/3 Combine
x = 5
x + y = 22 Substitute 5 for x
5 + y = 22 Subtract 5 from both sides.
5-5+y = 22-5
y = 17
