Question

4c+12=7c+10.38

Answer 1

3c = 1.62
c = .54

Answer 2

This is similar to the last problem you posted. What you have to do is get both the c's on one side and then the constants on the other.

4c + 12 = 7c + 10.38

To get both c's on one side, we will subtract by 4c.

4c - 4c + 12 = 7c - 4c + 10.38
0 + 12 = 3c + 10.38

Now we will subtract both sides by 10.38 to get the c term by itself.

12-10.38 = 3c + 10.38 - 10.38
1.62 = 3c

Now to get c by itself, we will divide both sides by 3.

1.62/3 = 3c/3

And since 3/3 = 1, what you have on the right side is 1c which equals c

1.62/3 = c
