What two numbers have a sum of 217 and a difference of 85?

**x = one number**

y = other number

y = other number

x + y = 217 {sum of two numbers is 217}

x - y = 85 {difference of two numbers is 85}

--------------

2x = 302 {added the two equations}

x = 151 {divided each side by 2}

x + y = 217 {first equation}

151 + y = 217 {substituted 151, in for x, into first equation}

y = 66 {subtracted 151 from each side}

**151 and 66**are the two numbers
