Rewriting the equation 680x + 10y - 1000 = 0 as a function of x will be x = = (1000 + 10y)/680
<h3>How to compute the equation?</h3>
The equation given is 680x+10y - 1000 = 0
We are to rewrite as a function of x. This will be:
680x + 10y - 1000 = 0
680x = 0 + 1000 - 10y
680x = 1000 + 10y
680x/680 = (1000 + 10y)/680
x = (1000 + 10y)/680
