Calculati diferența dintre produsul și suma numerelor x și y unde:
×=3z
y=t:6
z=5×(126-8×7:14)-210
t=60×25-[190×5-(4×35+27×14):7]×37:74
Va rog ajutorrrr
As vrea la nivel de clasa a cincea (Please)

Answer 1

z=5*(126-8*7/14)-210=5*(126-56/14)-210=58(126-4)-210=5*122-210=400deci x=3zdeci x=3*400=1200.t=1500-[950-(140+378)/7]*37/74=1500-(950-518/7)*37/74=1500-(950-74)*37/74=1500-876*37/74=1500-438=1062.y=t/6deci y=1062/6=177       x*y=1200*177=212400si x+y=1200+177=1377deci 212400-1377=211023
