Answer:

1

Step-by-step explanation:

to solve -15(2 - 3b) - 11(4b - 3), plug in -2 for b

-15(2 - 3(-2) - 11(4(-2) - 3) < subsitute -2 for b

-15(2 + 6) - 11 (-8 - 3) < add/ subtract terms in parentheses

-15(8) - 11(-11)  < multiply numbers

-120 + 121 = 1 < add

the solution to the equation is 1
