To solve the equation and find the unknown number, we need to determine which number, when multiplied by [tex]\(-1\)[/tex], gives [tex]\(-60\)[/tex].
Let's represent the unknown number by [tex]\( x \)[/tex]. The equation can be expressed as:
[tex]\[ -1 \cdot x = -60 \][/tex]
Now, to isolate [tex]\( x \)[/tex], we need to divide both sides of the equation by [tex]\(-1\)[/tex]:
[tex]\[ x = \frac{-60}{-1} \][/tex]
Dividing [tex]\(-60\)[/tex] by [tex]\(-1\)[/tex] yields:
[tex]\[ x = 60 \][/tex]
Thus, the number that, when multiplied by [tex]\(-1\)[/tex], equals [tex]\(-60\)[/tex] is [tex]\(60\)[/tex].
