HE=x
L=32-x
so x+32-x=32 and
138*x+96(32-x)=4290
138+3072-96x=4290
42x=1218
x=29 heavy equipment operators @138=$4002 ANSWER
32-x=3 general laborers @96=$288 ANSWER
Adds to 4290

~~~~~~~~~~~~~~~~~~~~

Let x = number of heavy equipment operators employed Then 32-x = number of laborers employed 138x + 96(32-x) = 4290 138x + 96*32 - 96x = 4290 (138-96)*x = 4290 - 96*32 x = = 29. 32 - x =3 number of heavy equipment operators employed = 29 number of laborers employed = 3 Check. 29*138 + 3*96 = 4290. ! Correct !
