Answer:
<h2>1. {x | 1 < x < 3}</h2>
Step-by-step explanation:
x + 2 < 5 <em>subtract 2 from both sides</em>
x + 2 - 2 < 5 - 2
x < 3
x - 7 > -6 <em>add 7 to both sides</em>
x > 1
From x < 3 and x > 1 we have 1 < x < 3
Let’s make an equation
Let’s say x = amount of years after
Smith = 8, mother = 42

24 + 3x = 42 + x
2x = 18, x = 9
Solution: after 9 years
