What is the valuee of x

The value of x in this equation is 0. Just kidding bruv, you need an attachment. The value of the variable x varies within each equation. Such as, -5x+9=2(x+7), x could be anything, but you'd have to solve some of the other parts first.

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
