Question

−11b+7=40
solve for b

Answer 1

Explanation:

subtract 7 on both sides

40-7=33

-11b=33

divide -11 on both sides

b=-3

Answer 2

B=-3

Explanation:

-11b+7=40

Subtract -7 from both sides

-11b-7=40-7

11b=33

divide by -11

11b/-11=33/-11

-11 and -11 cancel out, leaving you with B=-33/11

thus B=-3
