Question

solve the equations -6g+12f=-9 and 14g-4f=-55​

Answer 1

Step-by-step explanation:

-6g+12f=-9 .... (1)

14g-4f=-55 .... (2)

(2)×3 = 42g - 12f = - 165.......(3)

(1) = -6g + 12f = - 9

_____________

(1) + (3)= 36g = -174

= g = -174/36

= g = -87/18

sub. g in (1),

-6 (-87/18) + 12f = -9

87/3 + 12f = -9

12f = -9 - 87/3

f = - (114/3)(1/12)

f = - 57/18
