funny thing about general discussion is that you can ask or talk about anything... even homework  anyway, i was wondering if there was an easier way to do this: -5d - 24= -4(d + 6) - d .My teacher offered me some help but she always gets way to technical and i don't understand what she is saying  Anyway, just needed alittle help with this kinda thing. Mrs. Vanderslice is giving out a big test at the end of the year primarily based on equations and inequalities. Signed, Whiteman |

well first you distribute the -4 so you get -5d-24=-4d-24-d combine like terms: -5d-24=-5d-24 add 5d: -24=d-24 +24: 0=d It's basic algebra. I can help with a ton of stuff if you need it. |

some basic things i do in my head in algebra 2: (-32y^15)^1/5 6√81x^4y^8 (23x^3+13x^2-8x) (14x^4+-10x^2) <--- this one i can't do in my head |

subtract -5d from both sides Simplify the equation after multiply each side by 1/5 The equation will now be isolated d = ?/? -> use calculator to translate fraction to number |

That's nothing here's and easy Limit question from Calc. Find the limit. Lim. x-5 x>5 x^2-25 |
