Answer:
x + y = 10
15x + 10y = 120
Step-by-step explanation:
The khakis and polos have to be added up to equal 10 like this: x + y = 10
Since it costs $15 for every khaki, multiply x by 15 like this: 15x
Since it cost $10 for every polo, multiply y by 10 like this: 10y
These all add up to $120, meaning we add up 15x and 10y to equal 120
15x + 10y = 120

Answer:
8x-8z
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
