Answer:
Step-by-step explanation:
<u>Let the number be x:</u>
- 2x = 5x + 12
- 2x - 5x = 12
- -3x = 12
- x = -4
It is -4
when two numbers have the same variable, we can add and subtract just like normal numbers.
12x + 8x = 20x - 3x = 17x
NO is 2 times LM
2(x+1) = 4x
2x + 2 = 4x
2 = 2x
1 = x
Plug that in for 4x
4(1)
4
Answer:
5x + 100

10x + 20 / 2 =
5x + 100
