Hi,
I.   2s+1p=$55
II.  1s+2{{{ highlight_green(p)}}}=$68   |Note used variable s rather than p

 2s+1p=$55
-2s - 4p = -$136     |Multiplying EQ II thru by -2 and adding to the 1st to eliminate s  (68*(-2) = -136)
        -3p = - $81, 
         p = $27, the cost of the slacks  
    {{{2s+27 = 55}}}  s = $14,cost of a shirt
