Answer 2

Substitution is where you solve for one of the variables and then plug that in for the same variable in the other equation. Here, there is already an equation that is solved for a variable, $\sf y=4x-11$. So we can plug in '4x - 11' for 'y' in the other equation:

$\sf 3x+5y=-9$

$\sf 3x+5(4x-11)=-9$

Distribute 5 into the parenthesis(multiply it to every term in the parenthesis):

$\boxed{\sf 3x+20x-55=-9}$

Your answer is C.
