document.write( "Question 4223: Question 4221: Hi, I asked a question on this set of equations a little while ago, but was wondering, could one use Cramers Rule to solve the following ..
\n" ); document.write( "a*4 + b*2 + c*9 + d * 7 = 21
\n" ); document.write( "a* 2 + b*5 + c*4 + d*4 = 11.5

\n" ); document.write( "a * 8 + b * 4 + c * 6 + d * 6 = 22
\n" ); document.write( "If so, I would be most grateful if someone could show me how ... or get me started anyway :)
\n" ); document.write( "And could a general 'formula' be created using this rule to solve other similar sets of equations?\r

\n" ); document.write( "\n" ); document.write( "I asked this question a little while ago and was asked if a*4 was a to the power of 4 or a times 4. Its a times 4 ... and the same applies to all the other unknowns in the equation. \n" ); document.write( "

You can put this solution on YOUR website!
i have sent you an explanation of Cramer's rule on the other posting of this question.\r
