Any odd multiple of 3 would be the counterexample of the given conjecture.

That is 3(2n - 1), for any natural number n, will be divisible by 3 but not divisible by 6 as 2 is not a factor.

<u>Examples:</u>

3(3) = 9

3(5) = 15

3(7) = 21 are some examples.

SashulF [63]

Answer:

Step-by-step explanation:

<em>START:</em> 4x + 10 = - 26 ⇔ 4x = - 36 ⇔ <em>x = - 9</em>

\frac{1}{2} x + 13 = 9 ⇔\frac{1}{2} x = - 4 ⇔ <em>x = 8</em>

\frac{3}{4} x - 9 = 27 ⇔ \frac{3}{4} x = 36 ⇔ <em>x = 48</em>

9 - 2x = 35 2x = - 35 + 9 ⇔ <em>x = - 13</em>

\frac{2}{3} x + 15 = 17 ⇔ \frac{2}{3} x = 2 ⇔ <em>x = 3</em>

- 5x - 10 = 10 ⇔ 5x = - 20 ⇔ <em>x = - 4</em>

Now is your turn. You can do it!!!

1. -10=xy+z, solve for x please? 2. h-4/j =k, solve for j please?​
ANEK [815]

Answer:

x=\frac{-10-z}{y}

Step-by-step explanation:

1 Subtract z from both sides.

-10-z=xy

2 Divide both sides by y

\frac{-10-z}{y} =x

3 Switch sides.

x=\frac{-10-z}{y}

2nd question

Answer: j=-\frac{4}{k-h}

Step-by-step explanation:

1 Subtract h from both sides

-\frac{4}{j} =k-h

2 Multiply both sides by j.

-4=(k-h)j

3 Divide both sides by k−h.

-\frac{4}{k-h}=j

4 Switch sides.

j=-\frac{4}{k-h}
