Make x the subject if formula in a/x +b/x=1

To make x the subject of the formula, we can start by combining the terms on the left side:

(a/x) + (b/x) = 1

To combine the terms, we need a common denominator, which is x in this case. So we can rewrite the equation as:

(a + b)/x = 1

Now, to isolate x, we can take the reciprocal of both sides:

x/(a + b) = 1

Finally, we can multiply both sides by (a + b) to solve for x:

x = (a + b)
