Best ResponseYou've already chosen the best response.0Attempt 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`.

Best ResponseYou've already chosen the best response.0Before adding or subtracting from both sides or anything like that, let's try to combine like terms first. \[\Large\rm \color{royalblue}{14}+3x\color{royalblue}{7}=\color{orangered}{7x}+7\color{orangered}{4x}\]
