 Posted: Mon Dec 30, 2002 9:14 pm    Post subject: 1 OK class, let's learn some algebra. a=a a+b=b+a a*b=b*a a*(b+c)=a*b+a*c If a=b and b=c then a=c If a=b then b=a a+0=a a*1=a a*0=0 IMPORTANT! If a=b: a+c=b+c a-c=b-c a*c=b*c a/c=b/c Also, if a=b and c=d: a+c=b+d a-c=b-d a*c=b*d a/c=b/d Solve all 12 of these equations/equation systems, and you pass. 1. x=0*x+42 2. x*1*1*1=61 3. x+6=8+6 4. 2(x+6)=100+x 5. 6*(3x+8)-7*(2x-11)=149 6. x+y=7+100, x-y=7-100 7. x+2y=10, 2x+y=11 8. 7x=3y-1, x-1=y 9. 931-x=y+x, 911+x=y-x 10. x+y+z=10, x-y=1, z-y=6 11. §+¨=©+ª, §=¨+©+ª, §+¨+©=ª, §=¨+42 12. -9§+6¨+6©-3ª=-105, 2§+10¨-7©-6ª=3, 6§+10¨+10©+2ª=14, -9§+3¨+6©-10ª=-171 ------------------ GL DPWestley: I had my backspace key removed and a beverage dispenser pur in it's place. See? I can't go back and fix "put." GLmathgrant: I once was banned from a M:TG tourney for bringing over 50 banned cards!
