Given:

[tex]\begin{gathered} y=3x+19\ldots\ldots\ldots(1) \\ y=5x+33​\ldots\ldots\ldots(2) \end{gathered}[/tex]

To solve: The system of equations by substitution

Explanation:

Substituting equation (1) in equation (2), we get

[tex]\begin{gathered} 3x+19=5x+33 \\ 3x-5x=33-19 \\ -2x=14 \\ x=-7 \end{gathered}[/tex]

Substitute the x value in equation (1), we get

[tex]\begin{gathered} y=3(-7)+19 \\ y=-21+19 \\ y=-2 \end{gathered}[/tex]

Final answers: The solutions are,

[tex]\begin{gathered} x=-7 \\ y=-2 \end{gathered}[/tex]
