Since 2x contains the variable to solve for, move it to the left-hand side of the equation by subtracting 2x from both sides.
Since x and -2x are like terms, add -2x to x to get -x.
Since -7 does not contain the variable to solve for, move it to the right-hand side of the equation by adding 7 to both sides.
Subtract 6 from 7 to get 1.
Multiply each term in the equation by -1.
Multiply -x by -1 to get x.
Multiply 1 by -1 to get -1.
