Answer: x=12

Step-by-step explanation:

You start with: 2x\neq 2x-12

The segment PQ is half of PR, so to make both sides equal the PQ side must be doubled.

2x=4x-24

Then all x-values should be put on one side of the equation.

2x-4x=-24

Combine like terms.

-2x=-24

Then simplify.x=12

Chet needs to buy 4 work shirts, all costing the same amount. The total cost before Chet applies a $25 gift certificate can be n
Alborosie
Let us use x as the cost before Chet would apply a $25 gift certificate. Based on the problem, we can see that the original cost of the product cannot be more than 75 which means that it can be equal to 75 or less than 75. We can actually express the inequality as x< or = 75 since we are looking for the cost before Chet applied the $25 gift certificate. This means that we do not need to add in the 25 yet since the question asks for the cost before the application of the discount. - Credits, <span>Taskmasters and Hegans</span>
