(3n-4)=3(n+4)
3n-4=3n+12
no solution
There wouldn’t be a solution to this equation because the n cancels out when you subtract 3n-3n.
The first one is the best answer
X and y are books
x is fiction
y=nonifiction
x+y=36
x=12+y
12+y+y=26
2y+12=26
minus 12
2y=14
divide 2
y=7
sub
x=12+y
x=12+7
x=19
nonfiction=7
Alright, lets get started.
space that is 7.0 cm long and 4.0 cm wide it means space is in rectangular shape.
The lenght of the space = 7 cm
The width of the shape = 4 cm
The formula of area of rectange = length * width
The area of rectange = 
The area of rectange = 28 square cm
So, the area of the space you are aiming for 28 square cm. : Answer
Hope it will help :)
