Taking into account that their ages are:

  • Alvin=.....................x+11
  • Elga=.......................x

x + 11 + x = 107

Step 1: Simplify both sides of the equation.

x + 11 + x = 107

(x + x) + (11) = 107 (Combine Like Terms)

2x + 11 = 107

Subtract 11 from both sides.

2x + 11 − 11 = 107 − 11

2x = 96

Divide both sides by 2.

2x/2 = 96/2

x = 48

Answer: Olga's age is 48 years.✅
