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
