    Do you know what perimeter means?

    x+(x−4)+(x−4)=19

    The perimeter means you add up all the three sides.

    @misssunshinexxoxo To be honest i'm not sure. I don't know how to work it out.

    So, what is `4 inches less than x` mean? (In like an equation)

    \[4<x\]

    No, that means `x-4` 4 inches less than x means we have to do subtraction.

    so 19-4?

    So two of this sides are \(\sf x-4\) and one side is x So that means since the perimeter equals to 19: \(\sf\Large (x-4) + (x-4) + x=19\)

    So it would be 9?

    \(\sf\Large (x-4) + (x-4) + x=19\) we can make that: \(\sf\Large x-4 + x - 4 + x = 19\) Add like terms and then isolate x.

    (x+x+x)+(−4+−4)=19 there are 3 x's. -4+-4=-8 3x+−8=19 3x−8=19 then I added 8 to both sides. 3x=27 then I divide both sides by 3 x=9
