Step 1.1

Replace all occurrences of $y$ in $y - 2 x = - 3$ with $2 x - 3$ .

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

$y = 2 x - 3$

Step 1.2

Step 1.2.1.1

Subtract $2 x$ from $2 x$ .

$0 - 3 = - 3$

$y = 2 x - 3$

Step 1.2.1.2

Subtract $3$ from $0$ .

$- 3 = - 3$

$y = 2 x - 3$

$- 3 = - 3$

$y = 2 x - 3$

$- 3 = - 3$

$y = 2 x - 3$

$- 3 = - 3$

$y = 2 x - 3$

Step 2

Remove any equations from the system that are always true.

$y = 2 x - 3$
