Answ#$%^&* Im just joking but is that the hole Question thank you
Step-by-step explanation:
Lets x = Mary's age
Emily is there years older than twice her sister Mary's age = 2x + 3
Sum of both is less than 30:
x + 2x + 3 < 30
Solve for x
3x + 3 < 30
3x < 27
x < 9
Mary's age = 9
Inequality represents Mary's possible age:
0 < x < 9
Answer is the second one
0 < x < 9
2+x = 2x -15
2+15=2x - x
17 = x
