We can follow the following steps to make an equation and solve it.
Step 1:
five less than 13 means we have to subtract 5 from 13
so it becomes 13-5
Step 2:
A number y is five less than thirteen.
Now in algebraic expressions, "is" stands for "="
So we have:
Step 3:
Solving the equation to find y.
Subtracting 5 from 13, we get :
y=8
Answer:
For the given equation the solution is y=8.
