Well, first you should finish up the calculations within the brackets:
6=a(1-5)(1+3) becomes 6=a(-4)(4)
Then, simplify by multiplying the bracketed number together:
6=a(-4)(4) becomes 6=a(-16)
Finally, divide -16 from both sides to isolate a:
6=a(-16) becomes 6/-16=(a*-16)/-16, the -16's on the right side cancel
to leave a isolated and equal to 6/-16 or -3/8 or -0.375, and yer done!
+128599 6 = a(1-5)(1+3) simplify
6 = a(-4)(4)
6 = a (-16) divide both sides by -16
-6/16 = a = -3/8
