Anyone know the answer and the check to the equation 7 - 4c = 3c - 7 ?
Gelneren [198K]

Answer:

c=2

Step-by-step explanation:

7-4c=3c-7

7+7=3c+4c

14=7c

Dividing both sides by 7

c=2

CHECK:

Putting c in the above equation

7-4(2)=3(2)-7

7-8=6-7

-1=-1

Hence the above solution satisfies the given equation

love history [14]

Answer:

All real numbers

Step-by-step explanation:
