We want to find and solve an equation by following a given statement.
We will see that the number is 9.
Now let's see how we got that.
The statement says:
"Eighty decreased by three times a number is the same as five times the number increased by eight"
if we define x as "the number" then we can write:
80 - 3*x = 5*x + 8
We found the equation, now is time to solve it, remember that it means isolating x in one side of the equation:
80 - 3*x = 5*x + 8
80 - 8 = 5*x + 3*x
72 = 8*x
72/8 = x
9 = x
Then the number we wanted to find is 9.
