Brandon is 9 years older than Ronda. In four years, the sum of their ages will be 91. How old they now?
I need help step by step solution please

Step-by-step 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

true !
