2 I + S 3.-1 4x - 3 2r +1 What value of x makes ASTWAXYZ? S 3r +1 > 4r- x = 1 X = 2 x=3 X = 4

we know that
If two figures are congruent, then its corresponding sides and its corresponding angles are congruent
so
In this problem
ST=XY
SW=ZX
YW=YZ
Solve any of the three
SY=XY
substitute the given values
3x-1=4x-5
solve for x
4x-3x=-1+5
