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

Answer:
6x²+4x
Step-by-step explanation:
The given expressions are 3x²- 4x-4 and 3x²+8x+4.
We need to add these two expressions.
3x²- 4x-4 + 3x²+8x+4 = 3x² + 3x² -4x+8x-4+4
= 6x²+4x
On adding the given expressions, we get the value as 6x²+4x. Hence, the sum of the given expressions is equal to 6x²+4x
