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

Answers

Answer:

7

Step-by-step 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

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

collect like terms

$-9x+4+12+18x>79\n\n-9x+18x+4+12>79\n\n9x+16>79\n\n$

subtract 16 from both sides

$9x+16>79\n\n9x>79-16\n\n9x>63$

divide both sides by 9 we have

$x>(63)/(9)\n\n x>7$

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

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

A ray of light is the direction that light energy moves through a medium. It is represented by a line that is straight and has an arrow on it
