Eighty decreased by three times a number is the same as five times the number increased by eight find the number

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.
