Answer:

y= 6

Step-by-step explanation:

First you substitute in the 8 for x. you then multiply 8 times 8 which equals 64. you subtract 64 from 4 and 64, since it would be the opposite of addition. you would then take the -10y=-60, and you would divide by negative 10 to get y by itself. since negative 60 divided by negative 10 is a positive 6, your answer would be y equals 6.

A is the correct answer. A coefficient is just a number that appears in front of a variable. Please note that a number that doesn't have a variable behind it is still a coefficient since there is technically a variable behind it with a power of 0.
