b)-3.x - 2. y = 7 (х)

c)4. a + 7.b = -3 (b) ​

Answer 1

Respuesta:

$a ) 2m - p = 5\\2m = 5 + p\\m = 5 - 2 + p\\m = 3 + p\\\\- 3x - 2y = 7\\y = - 7 + 2y\\y = - 7 / 2\\y = - 3.5\\- 3x = 7 + 3.5\\- 3x = 10.5\\x = 10.5 / - 3\\x = - 3.5\\10.5 - 3.5 = 7\\\\4a + 7b = - 3\\b = 3 / - 7\\b = - 0.42857\\4a = - 3 + 0.42857\\4a = - 2.57143\\a = - 2.57143 / 4\\a = - 0.64285\\- 2.57143 - 0.42857 = - 3$
