Solve the system by substitution. If the system is inconsistent and has no solution, state this. If the system is dependent, write the form of the solution for any real number $x$.
-$y=6 x+40$
$7 x+5 y=-59$
A) $(-7,-2)$
B) $(7,2)$
C) Dependent, $(x, 6 x+40)$
D) Inøonsistent, $\varnothing$

Substitute $y$ from the first equation into the second equation: $7x + 5(6x + 40) = -59$. Simplify and solve for $x$, then use the value of $x$ to find $y$. The solution is $(-7, -2)$.
