[tex]\begin{bmatrix}x+y+z=174\\ y=x+2\\ z=y+2\end{bmatrix}[/tex]
Sustituimos datos
[tex]z=y+2[/tex]
[tex]\begin{bmatrix}y=x+2\\ x+y+y+2=174\end{bmatrix}[/tex]
[tex]\begin{bmatrix}y=x+2\\ x+2y+2=174\end{bmatrix}[/tex]
[tex]y=x+2[/tex]
[tex]\begin{bmatrix}x+2\left(x+2\right)+2=174\end{bmatrix}[/tex]
Resolvemos ecuación
[tex]x+2\left(x+2\right)+2=174[/tex]
[tex]3x+6=174[/tex]
[tex]3x=174-6\\3x=168\\x=168/3\\x=56[/tex]
Ahora solo remplazamos "x" en las demás variables
[tex]y=x+2\\y=56+2\\y=58[/tex]

[tex]z=y+2\\z=58+2\\z=60[/tex]
