Question

Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s).

Answer 1

If we divide both sides by -2, we have

$bx-5 = -8 \iff bx = -3 \iff x = -\dfrac{3}{b}$

So, if you choose b=3, you have x = -3/3=-1

Answer 2

Answer:

a)

       The value of x in terms of b is:

                $x=\dfrac{-3}{b}$

b)

         The value of x when b is 3 is:

                      $x=-1$

Step-by-step explanation:

We are given a equation in terms of x and b as follows:

           $-2(bx-5)=16-----------(1)$

a)

Now on simplifying the equation i.e. we solve for x i.e. we find the value of x in terms of b as follows:

On dividing both side of the equation by -2 we get:

$bx-5=-8$

Now on adding both side by 5 we get:

$bx=-8+5\\\\\\bx=-3$

Now, on dividing both side of the equation by b we get:

          $x=\dfrac{-3}{b}------------(2)$

b)

when b=3 in equation (2) we have:

              $x=\dfrac{-3}{3}\\\\\\x=-1$
