Answer:

idk if this is right but if it is right can i have brainliest and if it is wrong then rate me a 1 and you can umm... report me if u want

Step-by-step explanation:

Let's solve for x.

6x+7y=13x

Step 1: Add -13x to both sides.

6x+7y+−13x=13x+−13x

−7x+7y=0

Step 2: Add -7y to both sides.

−7x+7y+−7y=0+−7y

−7x=−7y

Step 3: Divide both sides by -7.

−7x

−7

−7y

−7

x=y
