So there's two small math facts you need to recall that make this work. One: Dividing by something is the same as multiplying by its reciprocal. And two: When you have an equation and you perform some operation on one side, you must always perform that same operation on the other side. Keeping these two facts in mind, what happens if you start with y = kx and divide by k?
When we solve an equation for one symbol, the result acts like a formula for that symbol. We generally write formulas with the isolated symbol on the left-hand side of the equation.why change the sides of x and y on the other sides of the equal sign, from y(1/k) = x to x = (1/k)y?
