4y-36=12
=> 4(y-9)=4(3)
=> y-9=3
=> y-9-3=0
=> y-12=0
=> y-12+12=0+12
=> y=12.
CHECKING OF ANSWER:-
AS; y=12
=> 4(12)-36=12
=> 48-36=12
=> 12=12
which is an right answer.

4y - 36 = 12
Add the number 36 to 36 and the number 36 to 12.
The 36 cancels out and the 12 equals 48 so the problem would now be
4y = 48
Then you do 4y divided by 4 and 48 divided by 4. The 4 in 4y cancels out to leave y. 48/4 = 12 So
y = 12

4y - 36 = 12. This means that 4 x y - 36 = 12. Therefore, y = 12.
This is a very simple algebra problem.

4y - 36 = 12
4y - 36 + 36 = 12 + 36
4y = 48
4y/4 = 48/4
y = 12

Isolate the variable - basically that means do some reverse operations to get the y by itself. For example, you're subtracting 36 from the left, so if you add 36 to both the left and the right (you have to do the same to both sides of the equation or else you change the overall value), you're getting rid of it and you're left with 4y. Follow these and see if it makes sense:
4y - 36 = 12
4y - 36 + 36 = 12 + 36
4y = 48
4y/4 = 48/4
y = 12
And just to be sure of yourself, plug in 12 into your original equation to see if it comes out to be a true statement. If not, then you'd have to recheck your work.

4y - 36 = 12
4y = 12 + 36(when u bring 36 to the other side)
4y = 48
y = 48/4(when u bring 4 to the other side coz 4y means 4*y)
y = 12

4y - 36 = 12
4y = 12+36
4y = 48
y = 48/4
y = 12

4y - 36 = 12
dividing equation by 4,
we get,
=> y - 9 = 3
=> y = 3 + 9
=> y = 12 Ans
