Answer:

it's -20

Step-by-step explanation:

-20 - 10 = -30 because of the negative signs

2(-20+5) = 2(-15) it's -15 as - and + = - and 20-5 is 15 ww then put the negative as -20 is the bigger number so ww have to put the sign of it, that will then be -15

at this point it's -30 = 2(-15)

2 x -15 is -30

-30 = -30
