remember the equal sign is there to tell you that the left is equal to the right. you can move, i say move but really we're subtracting and adding or multiplying or dividing from one side but you have to remember to do it to the other side as well.

zephyr141 · Answer

just keep doing that and you'll isolate the variable and solve the problem.
