Answer 1

Problem

11 less than 4 times a number is 55. Find the number. Please set up a key, set up the equation, and then solve the equation.

​

Solution

For this case the best equation would be:

4x -11= 55

Now we can solve for x, adding 11 in both sides we got:

4x = 66

And if we divide both sides by 4 we got:

x = 66/4 = 33/2 = 16.5
