Answer:
RESOLUTION
Step-by-step explanation:
Resolution is the smallest increment a tool can detect and display. For a nonelectrical example, consider two rulers.
First, we know that y is equal to -8x, so we can move the -8x to replace y in the first equation, then in the first equation we get -8x=6x-14, subtract 6x on both sides, -14x=-14, x=1
