[y+(-3)]+2=4
-2 -2
My golden rule is:"Do unto one side, the same as you do unto the other side of the equal sign".
I get rid of the +2 on the left by subtraction and therefore subtract 2 from the right.
y+(-3)= 2
+3 +3
Then I get rid of the -3 on the left by adding 3, and do the same on the right.
y=5

y = 5
Just work to put y on one side and numbers on the other:
[ y+(-3) ] +2=4
Subtract 2 from both sides:
y + (-3) + 2 - 2 = 4 - 2
y + (-3) = 2
Add 3 to both sides:
y + (-3) + 3 = 2 + 3
y = 5
Don't forget to double-check your answer.
Does [ y+(-3) ] +2 = 4?
[5 + (-3)] + 2 = 4?
(2) + 2 = 4?
4 = 4? Yes,
So the correct answer is y = 5.

Since there is one variable lets try and get the parenthesis by itself which leaves....
y - 3 = 2
Solve for y....
y = 5.
To check place the answer back into the equation and see if it works out.

Duh! simple question and some of the people got it wrong!!!
Y=5
How old are you to be asking these questions... Can you ask your math teacher for help? or maybe a tutor?
