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.

Solve inequality : 3x-2>4-3x and then graph the solution.
Note:
When we have an inequality with the symbols< or > , we use dotted lines to graph them. This is because we do not include the end point of the inequality.
