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

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: $b = -3$

To transform a mixed number to an improper fraction, we must multiply the denominator by the large number, and add the numerator.

So for $14\frac{2}{7}$ : $(14*7)+2=100$

But we also put this over the denominator in the mixed number, so we get: $\frac{100}{7}$ .

Then we do the same for $5\frac{2}{3}$ :

$(5*3)+2=\frac{17}{3}$

Then we must find a common denominator. Let's use 21 (multiply 3 and 7):

$\frac{100}{7} *\frac{3}{3}= \frac{300}{21}$

$\frac{17}{3}* \frac{7}{7} =\frac{119}{21}$

Now that we have a common denominator, we can subtract across:

$\frac{300}{21} -\frac{119}{21}= \frac{181}{21}$

Since $\frac{181}{21}$ cannot be reduced any further, we are going to leave this as our answer.

So the answer is $\frac{181}{21}$ .
