Given the system of equations. Which of the options represents the resulting equation after an equivalent expression for y is substituted into the second equation.

3 x - (5 x + 6) = 14
3(5 x + 6) - y = 14
-3 x(5 x + 6) + y = 6
-3 x + 5 x + 6 = 6

your answer would be 12

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.
