Cx+D=1/2 Equation?

Question

A equation is,Cx+D=1/2. Find the value of C and D.

Answer 1

Since you've only got one equation, and three literals standing in for numbers, there's no way to find a simple numerical value for x, C, or D... but we can express any of them "in terms of" the others, by solving for it.

For instance, we can solve the equation for D by simply subtracting Cx from both sides:

D = -Cx + 1/2 (or, equivalently, D = 1/2 - Cx)

If we want a numeric value for D, we need to know what numeric values C and x have.

Similarly, we can solve the original equation for C by, first, subtracting D from both sides:

Cx = -D + 1/2

and then dividing both sides by x:

C = (-D + 1/2) / x

The right side can be written in a couple of alternate ways:

C = -D/x + 1/2x
C = (-2D + 1)/2x

You can also solve the equation for x, but you weren't asked to do that. (Might be a good learning experience, though. :) )

Hope that helps!

Answer 2

One equation with two unknowns. There is insufficient information. The general formula for a straight line is: y = mx + c.
Matching the information up with a straight line gives:
y = mx + c
½ = cx + d

With more information this could be plotted to provide a range of values for c and d.

Answer 3

Cx+ D = 1/2
D= 1/2- Cx

Cx+ D = 1/2
Cx = 1/2 - D
C= (1/2 - D) / x

Answer 4

Too many unknowns for only 1 equation. It's impossible to solve.

You need to define x, in which case C & D could still take on a wide range of values.
