for this case we must apply distributive property to the following expression:

$-2 (2.1x + 3y-0.8)$

the distributive property states that:

$(a + b) (c + d) = ac + ad + bc + bd$

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

$-4.2x-6y + 1.6$

$-4.2x-6y + 1.6$
