Hi there!
There are two steps to take when solving this equation, but before we even think about that, let's start by rewriting the equation.
5a + 17 = 47
Step 1) Subtract 17 from both sides.
5a + 17 - 17 = 47 - 17
5a = 30
Step 2) Divide both sides by 5.
5a/5 = 30/5
a = 6
So, your final answer therefore is
a = 6
Hope this helps!
TIP - This method can be used when solving any equation with 1 variable. :D
Let a, ß be the roots of x² + 2ax + b =0.......[1]
⇒a + ß = -2a and aß = b
By hypothesis
la-ß | ≤ 2m
⇒ (a-ß)² ≤ 4m²
⇒ (a+ß)²-4aß < 4m²
⇒ 4a²-4b ≤ 4m²
⇒a² - b ≤ m²......(2)
And discriminant of (1) is >0
⇒4a²-4b> 0
⇒ b <a²...... (3)
From (2) and (3)
a² > b≥ (a² - m²)
b = [a² - m², a²)
