What do you mean "answer"? Do you want to know what the 3x - 2y + 5z is equal to? That is impossible to determine without the values of x, y, and z.
Do you want the solution? As in the values of x, y, and z that satisfy the equation? Well, first of all, it's not even an equation. If you set it equal to zero, as in 3x - 2y + 5z = 0, then it's an equation. But you cannot fully solve for x, y, or z. However, you could solve for each variable in terms of the others:
x = (2y-5z)/3
y = (3x+5z)/2
z = (2y-3x)/5
In order to solve for known values of x, y, and z, you would need at least three equations in these three variables.
I can tell you that this expression defines a plane in 3-dimensional space. The expression as it is fully defines the orientation of the plane, but you need to make it an equation (set it equal to some constant) to define its position. Say you set this expression equal to zero (3x - 2y + 5z = 0). From this equation, you could determine various sets of points in 3-dimensional space:
(x,y,z) =
(0,0,0)
(1,-1,-1)
(2,3,0)
(-1,1,1)
(4,1,-2)
(4,6,0)
(3,2,-1)
There are an infinite number of points that satisfy the equation, but they are all on the same 3-dimensional plane.

What is the sum of multiplication expressions?
The sum of multiplication expressions is the answer that you'd have, if you added together more than one multiplication expression. For example: 3 x 4 + 5 x 2 = A <--- A = the answer after you do/evaluate the expressions 12 + 10 = A 22 = A 22 is the sum of the above multiplication expressions (i.e. 3 x 4 plus 5 x 2)

What is the algebraic expression of the sum of x and 9?
The algebraic expression for the sum of x and 9 is x + 9. In this expression, x represents a variable that can take on any value, and 9 is a constant. When you add x and 9 together, you are combining the variable x with the constant 9 to get the sum. This expression can be simplified further if needed, but the basic form is x + 9.
When is the vector sum not equal in magnitude to the algebraic sum?
The magnitude of the vector sum will only equal the magnitude of algebraic sum, when the vectors are pointing in the same direction.
