$y = - 7$ $y = -7$

Simply substitute the value of $x$ $x$ into the equation.

$y = 2 x - 1$ $y = 2x -1$

$y = 2 \cdot (- 3) - 1$ $y = 2*(-3) - 1$

$y = - 6 - 1$ $y = -6 -1$

$y = - 7$ $y= -7$

$y = - 7$ $y=-7$

We have $y = 2 x - 1$ $y = 2x - 1$

And $x = - 3$ $x = -3$

Substituting the value of $x$ $x$ in the expression for $y$ $y$ ,

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

$\Rightarrow y = - 6 - 1$ $implies y = -6 - 1$

$\Rightarrow y = - 7$ $implies y = -7$
