Answer 1

Answer:

-4 / - 21 = - 20 / x

X = - 105

Step-by-step explanation:

-4 / - 21 = - 20 / x

4 / 21 = - 20 / x

-20 × 21 = 4 × x

-20 × 21 / 4 = x

-5 × 21 = x

-105 = x

$\frac{ -4 }{ -21 } = \frac{ -20 }{ x } \\ = -x\left(-4\right)=21\left(-20\right) \\ = 4x=21\left(-20\right) \\ = 4x=-420 \\ = x=\frac{-420}{4} \\ = x=-105$
