Hi there

-(-2a+13)+(-9-2)-(-7a-3)

-(-2a+13)-9a-2-(-7a-3)

Distribute the negative sign

-(-2a+13)-9a-2+-1(-7a-3)

-(-2a+13)+-9a+-2+-1(-7a)+(-1)(-3)

-(-2a+13)+-9a+-2+7a+3

Distribute

2a+-13+-9a+-2+7a+3

Combine like terms

2a+-13+-9a+-2+7a+3

(2a+-9a+7a)+(-13+-2+3)

=-12

Any questions ?

I hope that's help !
