Question

What is the largest value of x that is not a solution to:
-(9x-4)+12+18x>79

Answer 1

7

Explanation:

given the expression, we are expected to solve for the value of x

`-(9x-4)+12+18x>79`

we begin by opening the bracket

`-(9x-4)+12+18x>79\\\\-9x+4+12+18x>79\\\\`

collect like terms

`-9x+4+12+18x>79\\\\-9x+18x+4+12>79\\\\9x+16>79\\\\`

subtract 16 from both sides

`9x+16>79\\\\9x>79-16\\\\9x>63`

divide both sides by 9 we have

`x>(63)/(9)\\\\ x>7`

the greatest value of x that is not a solution is 7 since x is not equal to 7
