Homework problem!~!~!O alright4x-3y=33 where x=-4y-25So we'll substitute:4x-3y=334(-4y-25)-3y=33(-16y - 100) - 3y =33-16y - 3y = 33 + 100-19y = 133y = 133/-19y = -7So why is negative 7. to do it you simply replace or substitute whatever 'x' is. So x is given as -4y-25. After that you use some multiplication to foil out the answer so you get -16y - 100 - 3y = 33. Because we have variables 'y' mixed with other things we need the other things on one side and the variable on the other side in order to solve it, hence -16y - 3y = 133. After that we just say -19y = 133 and to get y we divide by -19.Ok now that you have y you can easily solve for x. Y is simply -7. So x becomes:4x - 3(-7) = 334x + 21 = 334x = 12x = 3Same thing here..we substituted -7 for y and we know solve for x. The main objective is to get the variable on one side and whole numbers on the other. So once you have 4x+21=33 you want to subtract 21 to both sides (from the left and right) to get x by itself. Then you divide by 4 to get x by itself completly.Final answer x=3 y=-7 Hope she passes! Programmers HowTo's -- [url]http://jhermiz.googlepages.com[/url] |

Our songs do not suck - we are victims of a pan European conspiracy. |

The Eastern Block is jamming the TV signals, so you are not actually hearing, or seeing, our act. Pity really as our song, this year, was absolutely fantastic. Kristen |
