Solve the following system of equations.

2x + y = 3
x = 2y - 1

$\color{#000000 }{ \displaystyle  2x + y = 3 \quad \Longrightarrow\quad2\color{#ff0000}{\left(2y-1\right)}+y=3 }$
$\color{#000000 }{ \displaystyle  x = 2y - 1}$

I am just showing you that given the second equation, you can substitute 2y-1 instead of x, into the first equation.
