21-6n+2(2n-5)-3n
First, multiply 2x2n and 2x-5
21-6n+4n-10-3n
Then rearrange the terms
4n-6n-3n+21-10
Then combine like terms
-5n+11
hope it helps!
you cannot show too much "work"
basically, you remove what is common to all of the factors, and then put brackets, as it will be multiplied back in, remember that when you multiply exponents with the same base, its same as adding them, so subtract to remove...
you can seperate two of the variables , then factor, then subtract the last one from those two, because it cannot be factored out , as in part2 #2
X*(-5)-2=-42
-5x-2=-42
-5x=-40
x=8
These are not proportional. In order for them to be proportional they need to be constant (sorry if i’m wrong about that) it can’t be proportional because of the extra .25 cents added to it causing it to not run through the origin.
