Answer:
2n - 7 = 3n - 3
Step-by-step explanation:
Just count the n's and the (-1)'s
Step-by-step explanation:
BC = AD (opposite sides in parallelogram is equal)
x + 8 = 2x + 1
8 - 1 = 2x - x
7 = x
x = 7
BC = x + 8 = 7 + 8 = 15
Answer:
D. Infinitely many solutions
Step-by-step explanation:

1.Since neither equation contains an isolated. However, we can isolate -y in the first equation by adding
to both sides.
Like this: 
ending up with 
2.Now, we can change y to a positive y. By doing so, we divide -y by the entire equation.
Like this 
Ending with 
3.Now, we can plug the expression
into the second equation as a substitute for y, and solve for x. Then, we can use x to calculate y.
Like this 
4. Since -2x+2x would cancel out and leave -30=-30. This is true because we know -30 equals -30 with no variable in sight.
