Răspuns:
a= 6
b= -1
c= - 22
Explicație pas cu pas:
[tex] \frac{ - 2}{3 } = \frac{a}{ - 9} = \frac{4b}{6} = \frac{14}{c + 1} [/tex]
[tex] \frac{ - 2}{3} = \frac{a}{ - 9} = > - 2 \times 9 = 3 \times a[/tex]
=> -2 × -9 = 3a
18 = 3a
a = 6
[tex] \frac{ - 2}{3 } = \frac{6}{ - 9} = \frac{4b}{6} = \frac{14}{c + 1} [/tex]
[tex] \frac{6}{ - 9} = \frac{4b}{6} = > - 9 \times 4b = 6 \times 6[/tex]
=> -36b = 36
b= -1
[tex] \frac{ - 2}{3 } = \frac{6}{ - 9} = \frac{ - 4}{6} = \frac{14}{c + 1} [/tex]
[tex] \frac{ - 4}{6} = \frac{14}{c + 1} = > - 4 \times (c + 1) = 6 \times 14[/tex]
=> -4 × (c+1) = 84
c+1 = 84: (-4)
c+1 = -21
c = - 22
