Solve the linear equation: x+x+2+x+4+x+6=-28. State the property that justifies your first step and why you chose it.

When I solved the equation I got the answer of

×=-10. However, I do not know what the property I need to state for my first step. Isn't it subtraction property of equality?

please help!!
