Do the same thing to both sides as long as not divide by zero

5y/6-2y/3+5=y
interesting
isolate the variable
subtract 5 from both sides
5y/6-2y/3=y-5
subtract y from both sides
5y/6-2y/3-y=-5
try to clear fractions by multplying by greatest common multiplue of 6,3, and 1 which happens to be 6
multiply both sides by 6
5y-(2 times 2y)-6y=-30
5y-4y-6y=-30
add like terms
-5y=-30
multiply -1
5y=30
divide both sides by 5
y=6
It is the answer D, because 9 it’s in all answers
A(x) = x^2 - 18x + 81
A(x) = (x - 9)(x - 9)
A(x) = (x - 9)^2
the length of the side is (x - 9)
The answer is 70/100ths i am pretty sure
24 - 3x = -27
therefore -3x = -27-24
-3x = -51
-x= -17
therefore x is 17
