To transform the equation \(10x - 12 - 8x = 4x + 15\) into the form \(x = a\), you can take the following steps:
- Add 12 to both sides of the equation and then simplify: This will help eliminate the constant term on the left side.
- Subtract 4x from both sides of the equation and then simplify: This will help to isolate the \(x\) terms on one side.
So the two selected options are:
- Add 12 to both sides of the equation and then simplify.
- Subtract 4x from both sides of the equation and then simplify.
