Solving a System of Equations. Solve the system, or show that it has no solution. If the system has infinitely many solutions, express them in ordered-pair form.\r

That's the most inefficient, most time-consuming, and most error-prone method I've ever seen one use to solve a system of equations, 
\n" ); document.write( "if I ever saw one. It is so inefficient and CONFUSING to the point where the woman who solved it got WRONG solutions. Her solutions
\n" ); document.write( "DO NOT SATISFY THE EQUATIONS, so IGNORE HER ENTIRE SOLUTION. Plus, why would someone even try to solve a fractional system by graphing? RIDICULOUS!\r
\n" ); document.write( "\n" ); document.write( "I assume the system is: \"matrix%281%2C3%2C+%283%2F4%29x+%2B+%281%2F2%29y%2C+%22=%22%2C+5%29\" ------ eq (i)
\n" ); document.write( " \"matrix%281%2C3%2C+%28-+1%2F4%29x+-+%283%2F2%29y%2C+%22=%22%2C+1%29\" ---- eq (ii)
\n" ); document.write( "Just multiply eq (ii) by 3 to get: \"matrix%281%2C3%2C+%28-+3%2F4%29x+-+%289%2F2%29y%2C+%22=%22%2C+3%29\" ---- eq (iii)
\n" ); document.write( "Adding eqs (i) & (iii) results in: \"matrix%281%2C3%2C+%281%2F2%29y+-+%289%2F2%29y%2C+%22=%22%2C+8%29\"
\n" ); document.write( "\"matrix%281%2C3%2C+%28-+8%2F2%29y%2C+%22=%22%2C+8%29\"

\n" ); document.write( "Substitute - 2 for y in any of the original equations and you should get: \"highlight_green%28matrix%281%2C3%2C+x%2C+%22=%22%2C+8%29%29\"
