Question

va rog ajutatima mie imi da cu rest

Answer 1

[48 + 50 x 100 : (28 : a + 6) - 14] x [(50 - 20) + (143 - 24)] = 42316
 
48 + 50 x 100 : (28 : a + 6) - 14 = 42316 : [(50 - 20) + (143 - 24)]
34 + 50 x 100 : (28 : a + 6) = 42316 : (30 + 119) = 42316 : 149 = 284
50 x 100 : (28 : a + 6) = 284 - 34 = 250
100 : (28 : a + 6) = 250 : 50 = 5
100 = 5 x (28:a + 6)
20 = 28:a + 6
28:a = 14
2:a = 1
a = 2
