It depends on the value of x. The x is a variable. To evaluate an expression, you need to have a value (number) to replace the x.
If you mean 2x = 28 then the value of x is 14
If you mean: 4 = 2x then the value of x = 2
If you mean: 2x-0.04 =1.24 then the value of x works out as 0.64

If you mean 2x = 28 then the value of x is 14
If you mean: 4 = 2x then the value of x = 2
Do you mean "what is the value of x when 3x - 2x = 15?" in that case, the value of x is 15
If you mean: 2x-0.04 =1.24 then the value of x works out as 0.64
To find the maximum value of 2x + 5y within the feasible region, you would need to evaluate the objective function at each corner point of the feasible region. The corner points are the vertices of the feasible region where the constraints intersect. Calculate the value of 2x + 5y at each corner point and identify the point where it is maximized. This point will give you the maximum value of 2x + 5y within the feasible region.
If you mean: -2x = -4 then the value of x is 2
2x - 4 = 12Add 4 to each side:2x = 16Divide each side by 2:x = 8
If you mean the value of 15-2x when x is 2 then it is: 15-4 = 11
2x-57 degrees = -55
If you mean: x-3 = 2x-8 then the value of x works out as 5
