Use the three steps to solve the problem. Joe is 10 years older than James. In 8 years, twice Joe's age will equal three times James's age. How old is each now? {James is yrs., Joe is yrs.}
x = Joe's age and y = James's age Joe is 10 years older than James - equation - x = y + 10 In 8 years twice Joe's age will equal three times James's age - equation - 2(x+8) = 3(y+8)
2(x+8) = 3(y+8) 2(y + 10 +8) = 3(y+8) { substitute y + 10 for x 2(y + 18) = 3(y + 8) 2y + 36 = 3y + 24 12 = y
