If △ABC≅△VXW then:
AB = VX
CB = WX
Evaluating:
[tex]\begin{bmatrix}2y+2z-40=z+y\\ 16z-13y-24=y+3z-44\end{bmatrix}[/tex]
Solving the first equation for y:
[tex]2y+2z-40=z+y[/tex]
[tex]2y - y +2z - z= 40[/tex]
y + z = 40
y = -z + 40
Substituying y = -z + 40 in the second equation:
[tex]16z-13\left(-z+40\right)-24=\left(-z+40\right)+3z-44[/tex]
[tex]29z-544=2z-4[/tex]
29z - 2z = 544 - 4
27z = 540
z = 540 / 27
z = 20
y = -20 + 40
y = 20
