You can put this solution on YOUR website! x-7=2x-6
Since 2x contains the variable to solve for, move it to the left-hand side of the equation by subtracting 2x from both sides.
x-7-2x=-6
Since x and -2x are like terms, add -2x to x to get -x.
-x-7=-6
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.
-x=7-6
Subtract 6 from 7 to get 1.
-x=1
Multiply each term in the equation by -1.
-x*-1=1*-1
Multiply -x by -1 to get x.
x=1*-1
Multiply 1 by -1 to get -1.
x=-1
