Ok, so first multiply (9b^3-2b) by 5.
Now, subtract 9b^3 from both sides.
so the first step would it be -45b^3=10b
Why the equal sign? IT's still a part of its original equation.
sorry it should be a + sign
i got 9b^3-45b^3=3b which would simplify to -36b^3=3b
Whoops sorry. I actually would't know; I can only do this on paper.
What happened to 7b and 2b (which was in the brackets)?
sorrrrrrrrrrrrrry no wounder i'm confused i wrote wrong problem it should be 9b^3+7b-5(9b^3-2b)
Next time please just enter the formula correctly. The humour in the question is appreciated, but makes the question confusing.
And is it 0=9b^3+7b-5(9b^3-2b)? That would make a lot more sense.
Im sorry im flipping from page to page and wrote it wrong but how did you get that cuz i got -36b^3+17b
No, no, yours sounds right. What I said it just the type of formula that it would be formatted at the beginning. I fully believe that your answer is probably correct. I myself can't check; sorry. I'm overwhelmed with work at my end.
oh no problem i thought you ment it =0 i was like OMG what did i do wrong lol
Ok. Well, good luck with your other questions then! I didn't really do much this round; nice work.
