document.write( "Question 767028: Question A) A company needs to clear 400ha of land. The company has newly acquired a D7 H bulldozer and is renting another bulldozer (D7R). A bulldozer consumes 200 litres of fuel per day and cost of fuel is 3350/litre. The two bulldozers have different conditions and work efficiency differs according to machine condition and operator. The company currently pays 1,200,000 UGX daily for the dry-hire bulldozer.\r

DETAILED EXPLANATION

\n" ); document.write( "
Look at .
Eliminated similar terms \"highlight_red%28+x+%29\",\"highlight_red%28+x+%29\",\"highlight_red%28+-x+%29\",\"highlight_red%28+2%2Ax+%29\" replacing them with \"highlight_green%28+%281%2B1-1%2B2%29%2Ax+%29\"
It becomes \"highlight_green%28+%281%2B1-1%2B2%29%2Ax+%29=6\".
\n" ); document.write( "
Look at .
Added fractions or integers together
It becomes \"%28highlight_green%28+3+%29%29%2Ax=6\".
\n" ); document.write( "
Look at \"highlight_red%28+%28highlight_red%28+3+%29%29%2Ax+%29=6\".
Remove unneeded parentheses around factor \"highlight_red%28+3+%29\"
It becomes \"highlight_green%28+3+%29%2Ax=6\".
\n" ); document.write( "
Look at \"3%2Ax=highlight_red%28+6+%29\".
Moved these terms to the left \"highlight_green%28+-6+%29\"
It becomes \"3%2Ax-highlight_green%28+6+%29=0\".
\n" ); document.write( "
Look at \"highlight_red%28+3%2Ax-6+%29=0\".
Solved linear equation \"highlight_red%28+3%2Ax-6=0+%29\" equivalent to 3*x-6 =0
It becomes \"highlight_green%28+0+%29=0\".
Result: \"0=0\"
