Question

# 3x + x + x + x - 3 – 2 = 7+ x + x

In the equation above, what is the value of x?

- 1
- 3

Hint:

### We solve this problem by doing some simple algebraic manipulations.

## The correct answers are: 1, 3

### Step 1 of 1:

The equation, given here, is

3x + x + x + + x – 3 – 2 = 7 + x + x

⇒ 3x + 3x - (3 + 2) = 7 + 2 x

⇒ 6x – 5 = 7 + 2x

⇒ 6x - 2x = 7 + 5

⇒ 4x = 12

⇒ x = 3

Final Answer:

The value of x is— D) 3.

A distance is generally the amount of space or length that separates two people, objects, or situations. For example, four meters separate two streetlight poles, for instance, as a distance measure.

Where **Distance = time × speed**

Example: We kept a safe distance between two objects. At the same time, we notice a new space between object one and object 2. Although once close, there was a significant gap between the objects. However, wishes to distance themself from the object's former boss.
