12-4=7.2%2Bc%2B4.8 Start with the given equation.


10%2812-4%29=10%287.2%2Bc%2B4.8%29 Multiply both sides by 10 to clear out the decimals.


120-40=72%2B10c%2B48 Distribute and multiply.


80=72%2B10c%2B48 Combine like terms on the left side.


80=10c%2B120 Combine like terms on the right side.


0=10c%2B120-80 Subtract 80 from both sides.


-10c=120-80 Subtract 10c from both sides.


-10c=40 Combine like terms on the right side.


c=%2840%29%2F%28-10%29 Divide both sides by -10 to isolate c.


c=-4 Reduce.
