 Question 711718: Mark is 8 years younger than Gerry. In ten years, he will be ten years more than one-half as old as Gerry. Find their present ages.Answer by stanbon(60778)   (Show Source): You can put this solution on YOUR website!Mark is 8 years younger than Gerry. In ten years, he will be ten years more than one-half as old as Gerry. Find their present ages. --------- Equations: m = g - 8 m+10 = (1/2)(g+10)+10 ------ Substitute for "m" and solve for "g": g-8+10 = (1/2)(g+10)+10 ------ g - 8 = (1/2)(g+10) 2g - 16 = g+10 g = 26 (Gerry's age now) ---- Solve for "m": m = g - 8 m = 24 years (Mark's age now) ----- Cheers, Stan H. ===========
