Answer:

Ronda is 37 and Brandon is 46

Explanation:

x - the age of Ronda

x + 9 - the age of Brandon

x + 4 - the age of Ronda in 4 years

x + 9 + 4 - the age of Brandon in 4 years

x + 4 + x + 9 + 4 - the sum of their ages in 4 years

x + 4 + x + 9 + 4 = 91

2x + 17 = 91 {subtract 17 from both sides}

2x = 74 {divide both sides by 2}

x = 37

x + 9 = 37 + 9 = 46
