Hope this helped :)
Easy you can't touch the subscripts so u need to add coiffents like a puzzle if you do this then it will chance this 1st name each element on each side then say how much it's worth then see what you need to chance like this
Ti=1
Cl=4
Mg=1.
On the other side
Ti=1
Mg=1
Cl=2. What do you need to change using coffients
