\begin{aligned}10x+3y+5z-t&=10
\\11x-y&=4\end{aligned}

You have a system of linear equations:

\[
\begin{aligned}
10x + 3y + 5z - t &= 10 \quad \text{(Equation 1)}\\
11x - y &= 4 \quad \text{(Equation 2)}
\end{aligned}
\]

To proceed with solving this system, we'll note the following:

1. **Equation 1** involves four variables \( x \), \( y \), \( z \), and \( t \).
2. **Equation 2** involves only two variables \( x \) and \( y \).

### Next Steps
To solve this system, we need more equations to find the exact values of \( x \), \( y \), \( z \), and \( t \). However, with the current equations, we can express some variables in terms of others:

1. **Solve Equation 2 for \( y \)**:
   \[
   y = 11x - 4
   \]

2. **Substitute \( y = 11x - 4 \) into Equation 1**:
   \[
   10x + 3(11x - 4) + 5z - t = 10
   \]
   Simplifying this:
   \[
   10x + 33x - 12 + 5z - t = 10
   \]
   \[
   43x + 5z - t = 22 \quad \text{(Equation 3)}
   \]

Now, we have:
- Equation 2: \( y = 11x - 4 \)
- Equation 3: \( 43x + 5z - t = 22 \)

This gives us expressions for \( y \) and a new relation between \( x \), \( z \), and \( t \). To find specific values for \( x \), \( y \), \( z \), and \( t \), we would need more equations.
