( a + a + 2 ) × 2 = 1312
a + a + 2 = 1312 : 2
a + a + 2 = 656
2a = 656 - 2
2a = 654
a = 654 : 2
a = 327
a + 2 = 327 + 2
a + 2 = 329
a + a + 2 = 1312 : 2
a + a + 2 = 656
2a = 656 - 2
2a = 654
a = 654 : 2
a = 327
a + 2 = 327 + 2
a + 2 = 329
2 ( a + b ) = 1312
b = a + 2
2 ( a + a + 2 ) = 1312
2 ( 2 · a + 2 ) = 1312
2 · a + 2 = 1312 : 2
2 · a + 2 = 656
2 · a = 656 - 2
2 · a =654
a = 654 : 2
a = 327
b = 327 + 2
b = 329
Verificare: 2 x ( 327 + 329 ) = 2 x 656 = 1312
Sper ca te-am ajutat!
