Question 161568
</pre><font size=4><b>
Number of bicycles={{{b=4x-1}}}, four times the no. of tricycles less 1
Number if tricycles={{{x}}}
So, number of wheels
{{{2(4x-1)+3x=174wheels}}}, EQN 1
{{{8x-2+3x=174}}}
{{{11x=174+2=176}}}
{{{cross(11)x/cross(11)=cross(176)16/cross(11)}}}
{{{x=16}}}, Number of tricycles
{{{4*16-1=64-1=63}}} Number of bicycles
check, via EQN 1
{{{2*63+3*16=174}}}
{{{126+48=174}}}
{{{174=174}}}
Thank you,
