Answer:


b = -3

Explanation:

Step 1: Subtract 7 from both sides


-11b + 7 - 7 = 40 - 7


-11b = 33

Step 2: Divide both sides by -11


-11b / -11 = 33 / -11


b = -3

Answer:
b = -3

Hey there!

-11b + 7 = 40

  • SUBTRACT by 7 on each of your sides.

-11b + 7 - 7 = 40 - 7

Cancel out: 7 - 7 because that gives you 0

Keep: 40 - 7 because it helps us solve for our answer

40 - 7 = 33

  • DIVIDE both sides by -11

11b/-11 = 33/-11

Cancel out: -11b/-11 because it equals 1

Keep: 33/-11 because it gives you -3

33/-11 = 33 ÷ -11 = 3

b = -3

Good luck on your assignment and enjoy your day!
