Answer:s = n(c - d)or s = c - dnsee belowStep-by-step explanation:Assuming this is the problem, which is what you wrote.[tex] d = c - \dfrac{s}{n} [/tex]d = c - s/nSwitch sides.c - s/n = dSubtract c from both sides.-s/n = d - cMultiply both sides by -n.s = n(c - d)If the problem is this:[tex] d = \dfrac{c - s}{n} [/tex]then the solution is:d = (c - s)/nSwitch sides:(c - s)/n = dMultiply both sides by n.c - s = dnSubtract c from both sides.-s = dn - cMultiply both sides by -1.s = c - dn
