Since you are not distributing at all, you can ignore the parenthesis :)
When ignoring the parenthesis your equation is
18x + 11 - 4x
Then just combine like terms :)
14x + 11
Your answer is C.
Hope this helped!
Answer : yes
Explanation yes
Answer is C because it's less than.
Distribute the ( ).....get -6y -10= -4
Add 10 on both sides, get -6y=6. Divide by-6, get y of -1
You can reword the equation 6x+y=9 to
Y=6x+9
Then plug-in y=6x+9 into the equation 2x+3y=-5
Plug this 2x+3(6x+9)=-5
2x+18x+27=-5
Then solve it from there
