Question: when you subtract like terms how do you know what number to subtract from the other? for example: 3x+4+10x-9=180, do I do 3x-10x or 10x-3x???​

You would add them together, not subtract.

Step-by-step explanation: When you’re combining like terms, you always “add“ them together. For that example, you would add 3x and 10x together along with 4 and -9 together. That would look like (3x + 10x) + [4 + (-9)], which simplifies to 13x - 5 = 180.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
