Answer:
Step-by-step explanation:
Actually, you can't. You could multiply the numerator and denominator of each 4/3 and 3/3 by 5, obtaining:
5(4) 5(3)
------ and --------
5(3) 5(3)
but this result has little practical value. 4/3 and 3/3 could be combined immediately, obtaining 7/3, if that's what you want to do, as the fractions already have the same denominator (3).
Answer: Fluffy's tail is 
m longer than Fireball's tail.
Step-by-step explanation:
Length of Fluffy's tail = 
m 
m
Length of Fireball's tail = 
m 
m
Difference = Length of Fluffy's tail - Length of Fireball's tail
Hence, Fluffy's tail is m longer than Fireball's tail.

Answer:
2 and 4, 4 and 8, 16 and 32
Step-by-step explanation:
Answer:
not the matrix equation but this works
x=4, y=1
Step-by-step explanation:
2x-4y=4 (original equation)
2(3x+2y=14) (do this so that you can subtract or add- it's still equal)
2x-4y=4 (original equation)
6x+4y=28 (after multiplying)
8x=32 (add 2 equations together to cancel out 4y, can also subtract)
x=4 (division)
2(4)-4y=4 (substitution)
8-4y=4 (multiplication)
4y=4 (addition/subtraction)
y=1 (division)
