Determine wether the given number is a solution of the given equation 10; 4-8x=-69
is 10 solution of the equation? yes or no

4 - 8x = - 69
-8x = -69 - 4
-8x = - 73
x = -73/-8
x = 9.125no, 10 is not a solution

or, instead of solving for x, we can just sub in 10 for x and see if it makes the equation true.

4 - 8x = -69
4 - 8(10) = -69
4 - 80 = -69
-76 = -69 (incorrect...therefore, it is not a solution)

38 dollars is your answer.
