if y+2=13 woudlnt you add 2 too both sides amd get y=15?

Subtract 2 from both sides.

so it would b 11 then

Right! :-)

To solve the equation y + 2 = 13, you can follow the steps:

Step 1: Notice that on the left side of the equation, there is a y term and a 2 term that are being added together. On the right side, there is a 13.

Step 2: To isolate the y term, you want to eliminate the 2 from the left side. The opposite operation to addition is subtraction. So, to remove the 2 from the left side, you subtract 2 from both sides of the equation.

By subtracting 2 from both sides of the equation, you get:

y + 2 - 2 = 13 - 2

Simplifying it further:

y + 0 = 11

y = 11

Therefore, the value of y that satisfies the equation y + 2 = 13 is y = 11.
