To find the best approximate solution of the system of linear equations given by \( y = 1.5x - 1 \) and \( y = 1 \), we can solve for \( x \) where these two equations intersect.
-
Set the equations equal to each other: \[ 1.5x - 1 = 1 \]
-
Solve for \( x \): \[ 1.5x = 1 + 1 \] \[ 1.5x = 2 \] \[ x = \frac{2}{1.5} = \frac{4}{3} \approx 1.33 \]
-
Now, substitute \( x \) back into either equation to find \( y \). We can use \( y = 1 \): \[ y = 1 \]
Thus, the approximate solution of the system of linear equations is \( (1.33, 1) \).
The answer is: (1.33, 1)
