if you mean XXI -- that is equal to 21
y = x2 - 4x + 3y = x -1Substitute the 2nd equation into the firstx -1 = x2 -4x + 3Rearranging:x2 -4x -x +3 +1 = 0x2 - 5x +4 = 0Solving this quadratic equation in x by factorising gives 2 values for xx1 = 4x2 = 1Substituting these into the original equation for y (y=x-1) givesy1 = 3y2 = 0So the 2 solutions to the equations are:x1=4y1=3andx2 = 1y2 = 0

it is equal to equal lol:P

That 8 might equal D. Trashed. "Eight Equals D" is: 8=D Which is a penis smiley -.- ~ Skullcandy88
these are the 9 sources of energy hope i helped you xx1. coal oil and gas2. nuclear energy3. hydroelectric energy4. solar energy5. wind energy6. biomass energy7. tidal energy8. wave energy9. geothermal energy
We are currently in the 21st century, thus the 8th century was 701-799. (Although some would dispute the first year as you imply, it is common to take the year xx1 rather than xx0.)

equals D repeater
(It's a penis) 8=====D 8 = balls D = head
