I'm probably late but I'm going to solve it anyway.
Let n = "a number." We will use it to translate the words into an equation.
"five times a number" translates to 5 * n or 5(n) or 5n. I will use the last one.
"minus - 11" is - (- 11)
"16 minus the number" is 16 - n
Now set everything in place and solve:
5n - (- 11) = 16 - n
First, simplify. The two negatives right next to each other, - (- 11) is like multiplying by a negative. A negative times a negative is a positive.
5n + 11 = 16 - n
Now, subtract 11 from both sides and add n to both sides to get constants on one side of the equal sign and variables on the other:
5n + n = 16 - 11
Combine like terms:
6n = 5
Divide by 6 on both sides to isolate the variable:
n = 5/6
Your number is 5/6
