Determine wether the given number is a solution of the given equation 10;4-8x=-69
2 answers:
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
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)
