Jan's age is 3 years less than twice tritt's age. the sum of their ages is 30. find their ages. write and solve the equation

Tritt's age is represented by x:
(x) Tritt + (2x-3) Jan = 30
x+2x-3=30
3x-3=30
3x=30+3
3x=33
x=33÷3
x=11
Tritt is 11 years old.
Jan is 2x-3 = 2(11)-3 = 22-3 = 19 years old.
11+19 is 30 (their ages together)
