How to solve 4x-c=k solve for x
Tresset [83]

Answer:

x = \frac{k + c}{4}

Step-by-step explanation:

<em><u>Given:</u></em>

4x - c = k

<em><u>Solve for:</u></em>

x

<em><u>Solution:</u></em>

(1) Let's move all of components that do not contain x (our target) to the right side (notice the change of sign of c from negative to positive):

4x = k + c

(2) Let's divide both sides of equation by 4:

\frac{4x}{4}  = \frac{k + c}{4}

(3) Now, we simplify the left side:

x = \frac{k + c}{4}

This is the solution.

Hope this helps!
