Question

1. 2x - 3y = -1\

y = x - 1

Explanation:

Step1: Substitute $y=x-1$ into first equation

$2x - 3(x-1) = -1$

Step2: Expand and simplify equation

$2x - 3x + 3 = -1$
$-x + 3 = -1$

Step3: Solve for $x$

$-x = -1 - 3$
$-x = -4$
$x = 4$

Step4: Find $y$ using $x=4$

$y = 4 - 1$
$y = 3$

Answer:

$x=4$, $y=3$
