Answer 1

Let's go through the steps you've outlined and solve for \( x \).

Starting with the equations:

1. \( y = 4x - 5 \)
2. \( x = -6y + 20 \)

We substitute \( y \) in the second equation:

\[ x = -6(4x - 5) + 20 \]

Next, distribute the -6:

\[ x = -24x + 30 + 20 \]

Combine the constants on the right side:

\[ x = -24x + 50 \]

Now, we'll add \( 24x \) to both sides to combine \( x \):

\[ x + 24x = 50 \]

This simplifies to:

\[ 25x = 50 \]

Now, divide both sides by 25:

\[ x = \frac{50}{25} \]

\[ x = 2 \]

Thus, the value of \( x \) is \( 2 \).
