Answer:

20x - 21y + 14

Step-by-step explanation:

$\rightarrow \sf (1)/(5) (150x - 80y + 50 - 50x - 25y + 20)$

collect like terms

$\rightarrow \sf (1)/(5) (150x-50x - 80y -25y + 50 + 20)$

add/subtract like terms

$\rightarrow \sf (1)/(5) (100x - 105y+70)$

distribute inside parenthesis

$\rightarrow \sf (1)/(5) (100x) + (1)/(5)( - 105y) + (1)/(5)(70)$

simplify the following

$\rightarrow \sf 20x -21y + 14$
