Question 252389
Good question!
We usually want to get an unknown variable (x for instance) on the left hand side of the equation and everything else on the right. We + - * / accordingly until the mission is accomplished.
a+b=c/d Find a, c and d.
.
a=c/d -b (subtract b from each side)
.
c=d(a+b) Multiply each side by d
.
d=c/(a+b) multiply each side by d/(a+b)
