Question

calculeaza x si y daca :x+y=226*3+589 x-y={624:2-30}:3

Answer 1

Cunoastem ca
x+y=226*3+589
x+y=678+589
x+y=1267

x-y=(624:2-30):3
x-y=282:3
x-y=94

Cunoastem ca:
x+y=1267
x-y=94
-----------(+)
2x=1361
x=680,5

y=1267-680,5
y=586,5

x+y=1267
680,5+586,5=1267 (verificat)

x-y=94
680,5-586,5=94 (verificat)
