Determine a solution for 1.5x - 2y = 8

1 answer

To determine a solution for the equation \( 1.5x - 2y = 8 \), we can express one variable in terms of the other or pick a value for one variable and solve for the other.

Let's solve for \( y \) in terms of \( x \):

  1. Start with the original equation:

    \[ 1.5x - 2y = 8 \]

  2. Rearrange the equation to isolate \( y \):

    \[ -2y = 8 - 1.5x \]

  3. Divide both sides by \(-2\):

    \[ y = \frac{1.5x - 8}{2} \]

This gives us the equation for \( y \) in terms of \( x \). Now we can pick a value for \( x \) to find a corresponding \( y \).

Let's choose \( x = 4 \):

  1. Substitute \( x = 4 \) into the equation:

    \[ y = \frac{1.5(4) - 8}{2} \]

  2. Calculate:

    \[ y = \frac{6 - 8}{2} = \frac{-2}{2} = -1 \]

Thus, one possible solution for the equation \( 1.5x - 2y = 8 \) is \( (x, y) = (4, -1) \).

If you want another solution, you can choose a different value for \( x \) or \( y \).
