PLEASEEEEEEE HELPPPPP

If their perimeters are equal, we can add up all the side lengths of each triangle, and set the perimeters equal to each other to find the value of x that satisfies the equation:
x - 2 + x + 3x + 1 = 2x - 5 + x + 4 + 6x - 7
Combine like terms:
5x - 1 = 9x - 8
And finally, solve for x:
7 = 4x
x = [tex]\frac{7}{4}[/tex]
Therefore, x is equal to [tex]\frac{7}{4}[/tex].
Hope this helps! :)
