Question

Método de igualacion 6a+5b=13
7a + 2b = -24​

Answer 1

6a + 5b = 13

7a + 2b = -24

a = 13 - 5b / 6

a= -24 - 2b / 7

13 - 5b - 24 - 2b

_____ = _______

6 7

7 (13 - 5b) = 6 (-24 - 2b)

91 - 35b = - 144 - 12b

-35b + 12b = - 144 - 91

(-) -23b = - 235

b = 235 / 23

b = 10.22

6a + 5b = 13

6a + 5(10.22) = 13

6a + 51 = 13

6a = 13 - 51

6a = -38

a = -38/6

a = -6.34

7a + 2b = -24

7a + 2(10.22) = -24

7a + 20.44 = -24

7a = -24 - 20.44

7a = - 44.44

a = -44.44/7

a = -6.34

a = -6.34 ; b = 10.22
