Question 316301
m= # of multiple choice questions
t= # of true false questions
this is set up just like money word problems
m is worth 3
t is worth 2
{{{m+t=28}}} # of ?'s, this says # of multiple choice questions plus # of true false questions equals 28 questions
{{{3m+2t=77}}}  point values, so the total points for m would be 3 times the # of questions and the total points for t would be 2 times the # of true false questions. those two point values added together make 77points.
<p>
so substitution or elimination method will work here

{{{m=28-t}}}
{{{3(28-t)+2t=77}}}
{{{84-3t+2t=77}}}
{{{84-t=77}}}
{{{7-t=0}}}
{{{highlight(7=t)}}}
{{{m=28-t}}}
{{{m=28-7}}}
{{{highlight(m=21)}}}
