Answer:
y=5
Step-by-step explanation:
Move all terms to the left
53y-55-(42y)=0
Add all the numbers together, and all the variables
11y-55=0
Move all terms containing y to the left, all other terms to the right
11y=55
y=55/11
y=5
-64 1/3
disregard the negative sign for the moment...
to turn a mixed number into an improper fraction, take ur whole number (63) and multiply it by ur denominator (3) and u get (64 * 3) = 192....now add that to ur numerator (1) and u get (192 + 1) = 193...now put that over ur original denominator (3) and u get 193/3.....now put ur negative sign back....and u have - 193/3.....simplified form, does not reduce
