✔ 最佳答案
- 14 = 6f + 12 - 2f
- 26 = 4f
f = - 26 / 4
f = - 6½

-14 = 6(f+2) - 2f
-14 = 6f + 12 - 2f
-14 = 4f + 12
-26 = 4f
f = -26/4
f = -6.5

-14=6(f+2)-2f
-14=6f+12-2f
-14-12=6f-2f
-26=4f
-26/4=f
-6.5
and that is the right answer because if you put it into the equation...

6(-6.5+2)-2*-6.5
6*-4.5-2*-6.5
-27-2*-6.5
-27+13
-14

6(f+2)-2f= -14
6f+12-2f= -14
4f+12= -14
4f+12-12= -14-12[subtracting 14 from both sides]
4f= -26
4f/4= -26/4[dividing both sides by 4]
f= -13/2= -6 1/2

And you want to know what f equals?

6(f + 2) - 2f = -14
6f + 12 - 2f = -14
4f = -26
f = -26/4
2007-12-22 12:55 pm
-14=6(f+2)-2f
-14=6f +12 - 2f
-14=4f +12
-14- 12=4f +12 - 12
-26=4f

f= -6.5
2007-12-22 12:54 pm
2f-2f-14=6
2f crosses itself out then ..
-14=6 bring over the six ..
-6-14
=8

i think :$ .. lol
