Answer: Huilan is 56 and Thomas is 50.
Explanation:
Huilan is represented by x and Thomas is represented by y...
x+y=106
x=6+y
We can use substitution since we have x by itself in the second equation. We know x is the same as 6+y, so we can substitute the x in the first equation for 6+y...
(6+y)+y=106.
Combine like terms...
6+2y=106.
Subtract 6 from both sides...
2y=100.
Divide by 2 on both sides...
y=50.
Thomas is 50.
Now that we know y, we can substitute it for 50.
x+(50)=106.
Subtract by 50 on both sides...
x=56.
Huilan is 56.
