We cannot help with algebra tiles here, sorry! :oops:

But we can help with traditional techniques for solving the equation:

Are you trying to solve for x? If so, use addition, subtraction and division (what you do to one side you must do to the other) to isolate x on one side.

I'll get you started.

-3x + 7 = -x - 1

add x to both sides

-3x + x + 7 = -x + x - 1

which, when simplified, gives you:

-2x + 7 = -1

keep going.....
