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

<h3><u>b</u><u> = -3 </u></h3>

Good luck on your assignment and enjoy your day!

Answer:

b = -3

Step-by-step explanation:

<u>Step 1:  Subtract 7 from both sides</u>

-11b + 7 - 7 = 40 - 7

-11b = 33

<u>Step 2:  Divide both sides by -11</u>

<u />-11b / -11 = 33 / -11

b = -3

Answer:  b = -3
