$x$ is multiplied by $-3$ and the result is subtracted from $20$: ___________.

Answer 1

Algebric operation:

$x$ is multiplied by $-3$ will give $-3x$

And the result is subtracted from $20$

So,

$$\begin{gathered} 20-(-3x) \\ =20+3x \end{gathered}$$

Hence,$x$ is multiplied by $-3$ and the result is subtracted from $20$ …$20+3x$…
