your answer would be
Step-by-step explanation:be (0.6x-0.8y)
Answer:
16.6 x − 14.8 y
Step-by-step explanation:
10 ( 0.4 x + 0.2 y ) + 21 ( 0.6 x − 0.8 y ) :
Simplify each term.
4 x + 2y + 12.6 x − 16.8 y
Simplify by adding terms.
Add 4 x and 12.6 x .
16.6 x + 2 y − 16.8 y
Subtract 16.8 y from 2 y .
16.6 x − 14.8 y.
