Question

completati cuun numar intreg, astfel incat ecuatia obtinuta sa aiba multimea solutiilor indicata:
a) ?x-70=0;S={5};
b) (-5)y-?=8;S={0};
c) ?:z=84;S={3};
d)x:?=25;S={-100}.
varog ajutatima e foarte urgent!!!!!!!!!!!!!!

Answer 1

a) ?x-70=0;S={5};
   14x-70=0

b) (-5)y-?=8;S={0};
b) (-5)y-(-8)=8;S={0}

c) ?:z=84;S={3};
c) 252:z=84;S={3};

d)x:?=25;S={-100}.
d)x:(-4)=25;S={-100}.
