 07-25-2007 #2 Blank Guest   Posts: n/a 8y-13x-8=48y = 12+13xy = 12/8 + 13/8x8p+3w = w -15 -2p10p=-2w-15p = -2/10 w - 15/10
 07-25-2007 #3 rick c Guest   Posts: n/a 8y - 13x - 8 + 13x + 8 = 4 + 13x + 88y/8 = (13x + 12)/8y = (13x + 12)/88p +3w -3w + 2p = w - 15 - 2p -3w + 2p10p = -2w - 15p = (-2w - 15)/10
 07-25-2007 #4 miggitymaggz Guest   Posts: n/a 8y-13x-8=4Add 8 to both sides: 8y-13x=12Add 13x to both sides: 8y=13x+12Divide 8 from both sides: y=(13/8)x+(12/8)Simplify: y=(13/8)x+(3/2)8p+3w=w-15-2pAdd 2p to both sides: 10p+3w=w-15Subtract 3w to both sides: 10p=-2w-15Divide 10 from both sides: p=-(2/10)w - 15/10Simplify: p=-(1/5)w-(3/2)
 07-25-2007 #5 Carmen Guest   Posts: n/a 8y-13x-8=4 isolate the 8y by adding 13x and 88y=13x+8+4combine like terms8y=13x+12divide everything by 8y=13/8x+12/8reduce 12/8 to 3/2y=13/8x+3/28p+3w=w-15-2pisolate 8p by subtracting 3w8p=-3w+w-15-2pcombine like terms8p=-2w-15-2padd 2p to both sides so you get p on one side10p=-2w-15divide everything by 10p=-2/10w-15/10reduce fractionsp=-1/5w-3/2
 07-25-2007 #6 mc23571 Guest   Posts: n/a 8y - 13x = 12 -13x = 12 / 8y /-x = 12 / 8y / -13x= -1(12/8y) / 13x= (12 / 8y) / 12x= = 8y 10p = -2wp= -2w / 10p= -w 1/5
 07-25-2007 #7 bnhawk03 Guest   Posts: n/a solving for y8y-13x-8=4 subtract 8y from both sides-13x-8=4-8y subtract 4 from both sides-13x-12=-8y divide by -8 on both sidestherefore y= (-13x-12)/-8solving for p8p+3w=w-15-2p add 2p to both sides10p+3w=w-15 subtract 3w from both sides10p=-2w-15 divide by 10 on both sidestherefore making p =p=-2/10w-15/10 and if you simplify the fractions you getp=-1/5w-3/2
