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 = 9.125 ... no, 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)

No because if you subtract 4 from - 69 it equals - 73. then if you put - 73 divided by - 8 it equals positive 9.125.

Or if you put in 10 where the x is you would do 4-8 * 10=-64

4-80=-69

-76=-69
