Answer:
Step-by-step explanation:
given the expression, we are expected to solve for the value of x
[tex]-(9x-4)+12+18x>79[/tex]
we begin by opening the bracket
[tex]-(9x-4)+12+18x>79\\\\-9x+4+12+18x>79\\\\[/tex]
collect like terms
[tex]-9x+4+12+18x>79\\\\-9x+18x+4+12>79\\\\9x+16>79\\\\[/tex]
subtract 16 from both sides
[tex]9x+16>79\\\\9x>79-16\\\\9x>63[/tex]
divide both sides by 9 we have
[tex]x>\frac{63}{9}\\\\ x>7[/tex]
the greatest value of x that is not a solution is 7 since x is not equal to 7
