The ages of Carl and Angela given from the expression is 25 years and 18 years respectively
Equation
- Angela's age = x
- Carl's age = x + 7
- sum of five times carl's age and four times angela's age is 197
5(x + 7) + 4x = 197
5x + 35 + 4x = 197
9x = 197 - 35
9x = 162
x = 162/9
x = 18
So,
Angela's age = x
= 18 years
Carl's age = x + 7
= 18 + 7
= 25 years
