Question

Afla valoriile literelor:
a+b+c=903; a+b=684; b+c=598

Answer 1

a + b + c = 903
a + b = 684
b + c = 598

684 + c = 903 ⇒ c = 903 - 684 ⇒ c = 219
b + c = 598 ⇒ b + 219 = 598 ⇒ b = 598 - 219 ⇒ b = 379
a + b = 684 ⇒ a + 379 = 684 ⇒ a = 684 - 379 ⇒ a =  305

Raspunsuri ⇒ a = 305
                   ⇒ b = 379
                   ⇒ c = 219

Answer 2

a+b+c=903
a+b    =684 =>c=903-684 =>c=219
    b+c+598 =>b=598-219 =>b=379
a=684-379
a=305
