How do you solve $y = - 6 x - 3$ $y=-6x-3$ and $y = 3$ $y=3$ using the substitution method?

$x = - 1$ $x=-1$

$y = 3$ $y=3$

Explanation:

$y = - 6 x - 3$ $y= -6x-3$
$y = 3$ $y=3$

Because of the transitive property...

$- 6 x - 3 = 3$ $-6x-3=3$

Add $3$ $3$ to both sides...

$- 6 x = 6$ $-6x=6$

Divide both sides by $- 6$ $-6$

$x = - 1$ $x=-1$
