  1. [tex] \large \rm \: \: - 63\\[/tex]
  2. [tex] \large \rm \: \: - \frac{3}{32} \\ [/tex]
  3. [tex] \large \rm \: \: 144 \\ [/tex]

FOR NUMBER 1:

[tex] \large \rm \: 1.) \: \frac{B}{9} = - 7 \\[/tex]

  • [tex] \large \rm \: \frac{B}{9} = - 7 \\ [/tex]
  • [tex] \large \rm \: B = - 7 \times 9[/tex]
  • [tex] \large \rm \: B = \green{ - 63}[/tex]

==========

FOR NUMBER 2:

[tex] \large \rm \: 2.) - \frac{3}{4x} = 8 \\ [/tex]

» First find the domain.

  • [tex] \large \rm \: - \frac{3}{4x} = 8[/tex]
  • [tex] \large \rm \: x≠0[/tex]

» Then Solve the equation.

  • [tex] \rm \: - \frac{3}{4x} = 8 \\ [/tex]
  • [tex] \rm \: - \frac{3x4x}{4x} = 8 \times 4x \\ [/tex]
  • [tex] \rm \: - 3 = 8 \times 4x \\ [/tex]
  • [tex] \rm \: 8 \times 4x = - 3 \\ [/tex]
  • [tex] \rm \: 32x = - 3 \\ [/tex]
  • [tex] \rm \: x = \green{ - \frac{3}{32} } \\ [/tex]

==========

FOR NUMBER 3:

[tex] \large \rm \: 3.) \: \frac{y}{12} = 12 \\ [/tex]

  • [tex] \rm \: \frac{y}{12} = 12 \\ [/tex]
  • [tex] \rm \: y = 12 \times 12 \\ [/tex]
  • [tex] \rm \: y = \green{144} \\ [/tex]
