Answer:

#y=8.7#

Explanation:

Given:#" "color(green)(y-5.8=2.9)#

Add #color(red)(5.8)# to both sides

#color(green)(y-5.8color(red)(+5.8)" "=" "2.9color(red)(+5.8))#

But #-5.8+5.8=0# giving:

#y+0=2.9+5.8#

#y= 8.7#

Answer:

Here is how...

Explanation:

First, PEMDAS. The image below explains what PEMDAS is...
Made by myself

You have to flip it around for SADMEP, because you are doing the exact opposite of an equation. So first, we start with subtraction and addition.

#y-5.8=2.9#
#y-5.8=2.9#
#+5.8=+5.8#
#color(magenta)(y=8.7)#

Now that is your answer.

If there was more to the equation, you could use all of PEMDAS, but this is a good example of a simple equation.
