Answer:

[tex]\sf x=\frac{3}{8}[/tex]

[tex]\sf \:y=\frac{171}{16}[/tex]

Step-by-step explanation:

[tex]\sf 7x+2y=24\\8x+27=30[/tex]

[tex]\sf 56x+16y=192\\ 8x=3[/tex]

[tex]\sf 56x+16y=192\\56x=21[/tex]

[tex]\sf 16y=171[/tex]

[tex]\sf y=\frac{171}{16}[/tex]

[tex]\sf 56x+16\times \frac{171}{16} =192[/tex]

[tex]\sf x=\frac{3}{8}[/tex]
