Answer:
A. -9n + 20
Step-by-step explanation:
First, distribute -5 to all terms within the parenthesis:
-5(2n - 4) + n
(-5 * 2n) + (-5 * -4) + n
-10n + 20 + n
Simplify. Combine like terms:
(-10n + n) + 20
(-9n) + 20
A. -9n + 20 is your answer.

Answer: x=11
Step-by-step explanation:
First, since angle A and angle B are vertical angles, that means that they are congruent. If they are congruent, then the m of angle A equals the measure of angle B. So, (3x+3)=(4x-8). Simplify using algebra so that in the end, you will find that x=11.
3x+3=4x-8
3=x-8
11=x
Answer: (-9,4)
Step-by-step explanation:
2x-y=-22
-7x+y=67
-5x=45
x=-9
2(-9)-y=-22
-18-y=-22
-y=-4
y=4
