$- 86 a - 32$ $-86a-32$

$- 5 (6 a + 5) + 7 (- 8 a - 1)$ $−5(6a+5)+7(-8a-1)$

Expand the brackets...

$- 30 a - 25 + (- 56 a) - 7$ $-30a-25+(-56a)-7$

And then collect the terms...

$- 30 a - 56 a = - 86 a$ $-30a-56a=-86a$

$- 25 - 7 = - 32$ $-25-7=-32$

And then place them together accordingly...

$- 86 a - 32$ $-86a-32$

How do you simplify -5(6a+5)+7(-8a-1)−5(6a+5)+7(−8a−1)-5(6a+5)+7(-8a-1)?
