<em>Additional comment</em>
If units are dimes, then the number would be +150. So, you see, <em>the units are important </em>to know.
It also depends on <em>what is increasing</em> and what is being represented by the integer. If it is an increase in debt, then the change in net worth might be -15.

5y - 1 = 4y + 5
5y -4y = 5 + 1
Y (1y) = 6
There are 152 men, 76 women and 38 children.
Step-by-step explanation:
Total persons = 266
Let,
men = m
women = w
children = c
According to given statement;
m+w+c=266 Eqn 1
m = 4c Eqn 2
w = 2c Eqn 3
Putting value of m and w from Eqn 2 and 3 in Eqn 1
Dividing both sides by 7
Putting c=38 in Eqn 2;
Putting c=38 in Eqn 1;
There are 152 men, 76 women and 38 children.
