Example

3(r+2s)=2t-4
a⋅(b-2)=3b
3(r+2s)=2t-4
a⋅(b-2)=3b

Question

$$\left( \frac{ 3 }{ -2 } , \right) 4$$

Answer

(-12)/2,

Solution


Move the negative sign to the left.
\[(-\frac{3}{2},)\times 4\]
Use this rule: \(\frac{a}{b} \times \frac{c}{d}=\frac{ac}{bd}\).
\[\frac{-3\times 4}{2,}\]
Simplify  \(-3\times 4\)  to  \(-12\).
\[\frac{-12}{2,}\]
