Answer:

[tex]x=18,\:y=6[/tex]

Step-by-step explanation:

Solve by substitution

[tex]\begin{bmatrix}x+y=24\\ 75x+60y=1710\end{bmatrix}[/tex]

[tex]\mathrm{Substitute\:}x=24-y[/tex]

[tex]\begin{bmatrix}75\left(24-y\right)+60y=1710\end{bmatrix}[/tex]

[tex]\begin{bmatrix}1800-15y=1710\end{bmatrix}[/tex]

[tex]\mathrm{For\:}x=24-y[/tex]

[tex]\mathrm{Substitute\:}y=6[/tex]

[tex]x=24-6[/tex]

[tex]x=18[/tex]

[tex]\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}[/tex]

[tex]x=18,\:y=6[/tex]
