Answer: No
Step-by-step explanation:
A variable is always denoted with a symbol (commonly x), and a variable means that it can change based on what you plug into the symbol
Constants must always stay the same, so variables can't be constants and constants can't be variables
Let Sara weight =x+25
amber wiegh =x
x+25+x=205
x= 90
Sara weight is 90+25= 115

Answer: 25
Step-by-step explanation:
Plug in x to the expression.
When there is the same base of exponents is being multiplied the exponents add together and the base stays the same.
So this simplifies to, 
.
This then solves to 25.
2x-6=2x+2
We move all terms to the left:
2x-6-(2x+2)=0
We get rid of parentheses
2x-2x-2-6=0
We add all the numbers together, and all the variables
-8!=0
There is no solution for this equation
