Answer:
C. x = 5

Explanation:
Step 1 - Simplify the equation by adding the common terms

3x - 7 + 4x = 28
3x + 4x - 7 = 28
7x - 7 = 28

Step 2 - Add seven to both sides of the equation

7x - 7 = 28
7x - 7 + 7 = 28 + 7
7x = 35

Step 3 - Divide both sides of the equation by seven

7x = 35
7x/ 7 = 35/ 7
x = 5

Therefore, the correct answer should be ‘c. x = 5.’

Answer:

x = 5

Step-by-step explanation:

3x - 7 + 4x = 28

Combine like terms

7x -7 = 28

Add 7 to each side

7x - 7 +7  = 28+7

7x = 35

Divide each side by 7

7x/7 = 35/7

x = 5

<h3>Answer:</h3>

2.25

<h3>Explanation:</h3>

Consider the square ...

... (x+a)² = x² +2ax +a²

The constant term (a²) is the square of half the x-coefficient: a² = (2a/2)².

The x-coefficient in your expression is 3. The square of half that is ...

... (3/2)² = 9/4 = 2.25

Adding 2.25 to both sides gives ...

... x² +3x + 2.25 = 6 + 2.25

... (x +1.5)² = 8.25 . . . . completed square
