Question 177071
</pre><font size=4><b>
Remember: {{{system(P[T]=s[1]+s[2]+s[3])}}}, working eqn
where------>{{{system(P[T]=37m,s[1]=x,s[2]=(1/2)x,s[3]=x-3)}}}
Then,
{{{37=x+(1/2)x+x-3}}}
{{{37+3=2x+(1/2)x}}}
{{{40=(4x+x)/2}}} cross multiply
{{{5x=40*2=80}}}------>{{{cross(5)x/cross(5)=cross(80)16/cross(5)}}}
{{{x=highlight(16m=s[1])}}}
{{{s[2]=(1/2)16=highlight(8m=s[2])}}}
{{{s[3]=16-3=highlight(13m=s[3])}}}
In doubt? Go back working eqn:
{{{37m=16m+8m+13m}}}
{{{37m=37m}}}
Thank you,
