Answer:
First question -> y = 2
Second question -> y = 10
Step-by-step explanation:
<u>Step 1: Solve y + 2 = 4</u>
Subtract 2 from both sides
y + 2 - 2 = 4 - 2
<em>y = 2</em>
<em />
<u>Step 2: Solve y - 2 = 8</u>
Add 2 to both sides
y - 2 + 2 = 8 + 2
<em>y = 10</em>
<em />
Answer: First question -> y = 2
Second question -> y = 10
