    Attempt to solve for x. If you end up with `x=#`, then it is `sometimes true`. This is telling us that the equation is true for ONE SPECIFIC X VALUE. If you end up with `5=6`, or something like that, then we have a false statement, 5 is never equal to 6, `never true`. If you end up with `3=3`, where both sides match, then your equation holds true for every x value, `always true`.

    Before adding or subtracting from both sides or anything like that, let's try to combine like terms first. \[\Large\rm \color{royalblue}{14}+3x\color{royalblue}{-7}=\color{orangered}{7x}+7\color{orangered}{-4x}\]

    you meant to write this? -7+3x=3x+7 Hmm no we shouldn't get a -7 on the left side. 14-7 = ?

    You got the same thing on both sides? 7+3x = 3x+7 mmm ok good, that's correct! :)
