Answer:
yes I believe it is a function
121 right because 87+34 is 121 but do i have to round the number
Expand the brackets first
-3y-12=21
add 12
-3y=33
divide by -3
y= -11
I think the question is supposed to be 3.6/y = 1.2/2
STEP 1: Divide 1.2 by 2 to get 0.6
3.6/y = 0.6
STEP 2: Multiply each term by y and simplify
3.6 = 0.6y
STEP 3: Since y is on the right side of the equation, switch the sides so it is on the left side of the equation
0.6y = 3.6
STEP 4: Divide each term by 0.6 and simplify
y = 6
SO, THE ANSWER IS...
y = 6
