Eric is ten years older than sal & mick is twice sals age their combined age equals 110 how old is sal

2x + x + 10 + x = 110

4x + 10 = 110 (Subtract ten from both sides)

4x = 100 (divide both sides by four)

x = 25

Plug in values to check ...

2 (25) + 25 + 25 + 10 = 110

50 + 50 + 10 = 110

110 = 110

Mick is 50 years of age.

Sal is 25 years of age.

Eric is 35 years of age.
