y = 3
Order of operations is PEMDAS - parenthesis, exponents, multiplication/division, addition/subtraction
First do everything inside of the parenthesis.
6 - 4 = 2
4 - 1 = 3
Once you do the stuff inside parenthesis, you can get rid of the parenthesis.
You now have y + 2 = 8 - 3
You don’t have any exponents, and don’t have to multiply/divide anything. You can subtract 8 and 3 though.
You now have y + 2 = 5
To find out what y equals, you want to isolate it on one side. To do this, subtract 2 from each side.
You get y = 3
