35.
a) 5•x+17•x= x•(5+17) = x•22
b) 6•a-18•b = 6•(a-3b)
c) 3•a+18•b-12•c = 3•(a+6b-4c)
36. x+y+z=17
a) 5•x+5•y+5•z= 5•(x+y+z) = 5•17= 85
b) 13•x+13•y+13•z-1313= 13•(x+y+z)-1313 = 13•17-1313 = 221-1313 = -1092
c) 882-3•(7•x+7•y+7•z) = 882-3•[7•(x+y+z)] = 882-3•(7•17)= 882-3•119 = 882-357 = 525
Sper ca te-am ajutat :)
