Which expression is equivalent to : n - 4.6n - 3.3n + 2.8n?

-4.1n

Step-by-step explanation:

Given the equation n - 4.6n - 3.3n + 2.8n, to get its equivalent expression, the following steps must be followed;

Step 1:

Factor out the common variable n

n (1 - 4.6 - 3.3 + 2.8)

Step 2:

Carry out the operation in parentheses;

= n (1+2.8-4.6-3.3)

= n (3.8-4.6-3.3)

= n (3.8-3.3-4.6)

= n (0.5-4.6)

= n (-4.1)

= - 4.1n

The equivalent expression is - 4.1n
