Answer:
[tex]-29[/tex]
solving steps:
[tex]\sf \hookrightarrow -\left(-4\right)\left(-6\right)-3/5\left(10+15\right)/1/3[/tex]
[tex]\sf \hookrightarrow -\left(-4\right)\left(-6\right)-3/5\cdot \:25/1/3[/tex]
[tex]\sf \hookrightarrow -24-3/5\cdot \:25/1/3[/tex]
[tex]\sf \hookrightarrow -24-5[/tex]
[tex]\sf \hookrightarrow -29[/tex]
