Question

solve the formula for the specified variable. a + b = s + r for r (a) r = s(a + b) (b) r = a + b - s (c) r = \frac{a + b}{s} (d) r = \frac{a}{s}+b question 5 last saved 3:13:39 pm

Explanation:

Step1: Isolate r

Subtract s from both sides of the equation $a + b=s + r$.
$a + b−s=s + r−s$

Step2: Simplify the equation

On the right - hand side, $s - s = 0$, so we get $r=a + b−s$.

Answer:

B. $r=a + b−s$
