Dados cuatro sistemas de ecuaciones. ¿Cuántos de los sistemas dados tienen infinitas soluciones?
\[
\begin{array}{c|c}
\text{\( \begin{aligned}
4x-6y+10z&=8 \\
-2x+3y-5z&=4 \\
x+y+z&=1
\end{aligned}\)}&
\text{\(
\begin{aligned}
4x-6y+10z&=8\\
6x-9y+15z&=12\\
x+y+z&=1\\
\end{aligned}\)}
\\\hline
\text{\(\begin{aligned}
4x-6y+10z&=8\\
-2x+3y+5z&=4\\
x+y+z&=1\\
\end{aligned}\)}&
\text{\(
\begin{aligned}
x+y+z&=1 \\
2x+2y+2z&=2 \\
-\frac x2-\frac y2-\frac z2&=-\frac12
\end{aligned}\)}
\end{array}
\]
\( 2 \)
\( 1 \)
\( 3 \)
\( 4 \)
