✔ 最佳答案
3 - 8c = -4 - c
3 - 8c + c = -4
-8c + c = -4 - 3
-7c = -7
c = -7/(-7)
c = 1

3 - 8c = -4 - c

ON REARRANGING THE TERMS WE GET THE FOLLOWING ..(LIKE TERMS ON ONE SIDE)

3+4 = -C+8C
7=7C

C=1

verification:
substituting the value of c in the equation given,
3-8(1)=-4-(1)
-5=-5
hence verified


Ans c=1

7=7c
c=1
God bless you.

It will be helpful if we put the one with c's on the same side. We will come up with this:

-8c + c = -4 - 3

By evaluating this:

- 7c = - 7
c = 1

Hope this helps! :)

3 - 8c = -4 - c

3-8c+c= -4
3-7c= -4
-7c = -4-3
-7c = -7
dividing by -7
c=1
