2 and 4.5 is not equivilant since 2 and 4.5 cannot go together (the 0.5 does not help and so it does not make it equivalent.)
Hope this helped!

Y = 180 - 51 -56 = 73
x = 180 - 73 - 72 = 35
x = 35 degrees
Answer: u should have at least i gallon per person per day
3y - 1 = 28

y= 9.66
Option A is the correct answer, y = x + 2
y - 3 = x-1
If you bring the 3 to the R.H.S, it becomes y = x + 2
If you substitute the values,
3 = 1 + 2
3 = 3
Thus, e equation is correct
