How do I go about solving this simple problem??*

**Jai**, Thursday, May 5, 2011 at 12:34am25s + 25 = -15s

first, we transpose all terms containing the variable s to one side of the equation (in this problem, let's transpose them to the left side), and all other terms to the other side.

thus, we transpose -15s to the left side. to transpose, we change its sign to the opposite, thus it becomes +15s on the left side, and the +25 becomes -25 on the right:

25s + 25 = -15s

25s + 15s = -25

then we combine similar terms. to combine terms with variables, we just add the numerical coefficient (the number before the variable), thus it becomes:

40s = -25

finally to get s alone, we divide both sides of equation by 40:

(40s)/40 = -25/40

s = -5/8

hope this helps~ :)
