5x-13=x-13<br><img src="https://tex.z-dn.net/?f=5x%20-%2013%20%3D%20x%20-%2013" id="TexFormula1" title="5x - 13 = x - 13" alt="5
Alecsey [184]

Answer:

x=0

Step-by-step explanation:

I must assume that your goal is to "solve for x."  State your goal explicitly each time you post a problem.

Combining like terms, we get 4x = 0, so that x = 0.

Check:  Is 5(0) - 13 = 0 - 13 true?  YES
