Answer #1

…akadeno. I seriously have no clue about the power of two and such. But if this were a math problem at the level of math im at the answer would be the same…Maybe we just learned mathematics diffrently. XD

Answer #2

6y-7-13y+21=0 -7y-7+21=0 -7y+14=0 -7y=14 y=-2 yepp

Answer #3

let’s see: 6y+(-13y)=-7y -7+21=14 -7y+14=0

 -14   -14

-7y=-14 divide all by -7 and you should get: y=2

Answer #4

sorry I forgot the negative sign so y=-2 oops :)

Answer #5

oh first I would minus to two y;s and get -7y and the -7+ 21 is 14 -7y=14 divide by -7 and y=-2… hop it helps!

Answer #6

Just wondering but is that equation correct… Doesnt seem right to me but maybe im just wrong.
