9In this video, I explain what I call the golden rule of first-degree equations: changing the sign (or not) when passing to the other side of the equation.
I'll show you how this is imagined in addition and multiplication.
A practical and clear lesson to demystify this essential concept of Basic Mathematics. Don't miss this opportunity to learn and master first-degree equations!
