Question

a - b = -3
3a + 3b = 58



ayuda por favor ¡¡¡¡¡

Answer 1

Respuesta:

Explicación paso a paso:

a - b = - 3 3a + 3b = 58

3 ( a + b ) = 58

a + b = 58/3

a - b = - 3 +

a + b = 58/3

-------------------

2a = 58/3 + 3

2a = 58+3.3/3

6a = 58 + 9

6a = 67

a = 67/6 a - b = - 3

67/6 + 3 = b

67+6.3/6 = b

67 + 18 = 6b

85 = 6b

85/6 = b
