9(m-2)=m+38
1. Distribute
9m-18=m+38
2. Add 18
9m=m+38+18
3. Simplify
9m=m+56
4. Subtract m from both sides
8m=56
5. Divide by 8 to both sides
m=7

Answer:
The two numbers are 7 and 11.
Step-by-step explanation:
x represent the first number.
y represent the second number.

2x = 22
x = 11
x - y = 4
(11) - y = 4
y = 7
