Eden Posted February 24, 2009 Report Share Posted February 24, 2009 Simultaneous Equations Help? I just can't grasp what to do: "Solve Simultaneously" "2x + 3y = 8" "3x + 2y = 7" I don't know if it really IS easy, but my teacher did it so complex on the board and he lost me. o.O Link to comment Share on other sites More sharing options...
zzazzb Posted February 24, 2009 Report Share Posted February 24, 2009 i'm not sure if your going to get how i explain, but i'll try (btw. what year are you in? i'm doing these atm ) first, you have to get either the Y's or the X's to the same amount. so say you want the X's to be equal, you times each line by the other so 3(2x + 3y = 8) 2(3x + 2y = 7) = 6x + 9y = 24 6x + 4y = 14 then subtract the botton line from the top to eliminate the X's 5y = 10 divide by 5 y = 2 THEN substitute y = 2 into either equation 2x + 3(2) = 8 2x + 6 = 8 minus 6 from each side 2x = 2 divide by 2 x = 1 i hope thats right.... and sorry if that made NO sence at all!

Can someone help with the names of the last three and tell me if the others are correct. The first three are right. Repetition of vowel sounds - Alliteration Sorry I only know that one. I'll add them if I figure out the other ones. Link to comment Share on other sites More sharing options...
Lise Posted February 25, 2009 Report Share Posted February 25, 2009 Katie, the last one is onomatopoeia (words which actually sound like the action/concept been discribed). Link to comment Share on other sites More sharing options...
Eden Posted February 26, 2009 Report Share Posted February 26, 2009 ^Yeah. Onomatopoeia. Words such as: sizzle, buzz, etc Link to comment Share on other sites More sharing options...
leah1234 Posted February 26, 2009 Report Share Posted February 26, 2009 I think that vowel sounds could be assonance Link to comment Share on other sites More sharing options...
Lise Posted February 28, 2009 Report Share Posted February 28, 2009 Assonance is repetition of vowel sounds to create internal rhyming within phrases or sentences, and together with alliteration and consonance serves as one of the building blocks of verse. For example, in the phrase "Do you like blue?", the "oo" (ou/ue) sound is repeated within the sentence and is assonant. Link to comment Share on other sites More sharing options...
