Answer:
3a+6+5/(a+2)
Step-by-step explanation:
To do this you replace x with a+2, meaning that 3x+5/x turns into 3(a+2)+5/a+2. Simplified this is 3a+6+5/(a+2)
Answer:
x = -4
Step-by-step explanation:
<u>Step 1: Subtract 2x from both sides</u>
2x - 2 - 2x = 4x + 6 - 2x
<em>-2 = 2x + 6</em>
<em />
<u>Step 2: Subtract 6 from both sides</u>
-2 - 6 = 2x + 6 - 6
<em>-8 = 2x</em>
<em />
<u>Step 3: Divide both sides by 2</u>
-8 / 2 = 2x / 2
<em>-4 = x</em>
<em />
Answer: x = -4
