Step-by-step explanation:
6x-3y-z+2x+3y-7z this equation goes to every step below.
since there are 2 opposites, add up to zero, remove them from the expression
-> 6x-z+2x-7z. (-3y. +3y)
collect like terms.
-> 8x-z-7z. (6x. +2x)
collect like terms.
-> 8x-8z

Answer:
1.02n
Step-by-step explanation:
A simplified version of this expression would be the following
1.02n
This is basically adding the n variables together. We do this by adding a 1 to the number being multiplied to n. This would basically add the 2% on top of what the original pay per hour is. We can prove that these two expressions are the same by substituting n for 10 in both expressions and solving them.
1.02n
1.02 * 10 = 10.2
n + 0.02n
10 + 0.02*10
10 + 0.2 = 10.2
