Question 935022
x = Jason's age now
x + 4 = Tanya's age now {Tanya is 4 years older than Jason}


x + 1 = Jason's age in one year
x + 5 = Tanya's age in one year


x + 5 = 2(x + 1) {in four years, Tanya will be twice Jason}
x + 5 = 2x + 2 {used distributive property}
x = 3 {subtracted x and subtracted 2 from each side}
x + 4 = 7 {substituted 3, in for x, into x + 4}


Jason is 3
Tanya is 7
