25s+25=15s
How do I go about solving this simple problem??*

25s + 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~ :)
