  • Opposite sides of parallelogram are equal

[tex]\\ \tt\hookrightarrow 9x-15=5x-3[/tex]

[tex]\\ \tt\hookrightarrow 9x-5x=-3+15[/tex]

[tex]\\ \tt\hookrightarrow 4x=12[/tex]

[tex]\\ \tt\hookrightarrow x=3[/tex]

Now

[tex]\\ \tt\hookrightarrow 3x-4=4y-2[/tex]

[tex]\\ \tt\hookrightarrow 3(3)-4=4y-2[/tex]

[tex]\\ \tt\hookrightarrow 9-4=4y-2[/tex]

[tex]\\ \tt\hookrightarrow 4y-2=5[/tex]

[tex]\\ \tt\hookrightarrow 4y=7[/tex]

[tex]\\ \tt\hookrightarrow y=7/4[/tex]
