Answer:
Explanation:
STEP 1:
-11b-4-(-b+3)....bracket the equation that you are subtracting and add a mins sign infront of the bracket because you are asked to subtract -b+3 from -11b-4.
STEP 2:
-11b-4+b-3
the minus sign infront of the bracket changes the minus sign to a positive (+)sign because a minus(-) timesed by a minus is a positive(+). and a minus timesed by a positive(+) is a negative(-)
STEP 3:
-10b-7
add the b values together(11b-b) = 10b
add the numericals together -4+(-3)= -7
STEP 4:
final answer is -10b-7
