Step-by-step explanation:
- 3x = 2x + 2
3x - 2x = 2
x = 2
2. 3x + 5 = 4x + 1
4x - 3x = 5 - 1
x = 4
3. 6x + 3 = 3x + 12
6x - 3x = 12 - 3
3x = 9
x = 3

Step-by-step explanation:
First of all, Elena is kinda dumb why put brochures on only 80%? Nevertheless, 400 letters will not contain a brochure. If you need an explanation just comment that you need one on this.
Answer:
The number is 12
Step-by-step explanation:
[] First, let's turn all these words into something mathematical. N will equal "my number"
-><u> If you add 12 to my number</u> and then multiply the result by 3, you will get 64 more than two-thirds of my number.
-> n + 12 <u>and then multiply the result by 3</u>, you will get 64 more than two-thirds of my number.
-> 3(n + 12), you will get 64 more than <u>two-thirds of my number</u>.
-> 3(n + 12) = <u>64 more than</u> 
-> 3(n + 12) = 64 + 
[] Phew, okay. Now it is something we can solve and less scary;
[Given]
3(n + 12) = 64 + 
[Distribute]
3n + 36 = 64 + 
[Multiply both sides by 3]
9n + 108 = 192 + 2n
[Subtract 108 and 2n from both sides]
7n = 84
[Divide both sides by 4]
n = 12
