Question 989888

We will use "x" to represent a number.


If 21 is added to a number --> (x + 21)

the result is 38 less than twice the number --> (= 2x - 38)


The equation:

x + 21 = 2x - 38


Solve,

x - 2x = -21 - 38

-x = -59 (divide both sides by -1)

x = 59 is the final answer.


If you plug x = 59 back into the equation both sides will be equal.
