Answer: 
Step-by-step explanation:
For this exercise you need to remember:
1) The mulitplication of signs:

2) By definition, like terms contain the same variables with the same exponent.
Then knowing this, and given the equations:
and 
You must subtract the like terms, which means that you must subtract the numerical coefficients of each term.
Then, you get the result is:

1/100
Each meter is 100 centimeter
Answer:
x=2
Step-by-step explanation:
x-5=5x-13
5x-x=-5+13
4x=8
x=8/4
x=2
2x+1=27032
2x=27031
x=13515.5
2x+3
=2(13515.5)+3
=27034
