Hey there!
1/2(8 - 6y) + 1/5(10y - 25)
DISTRIBUTE 1/2 & 1/5 WITHIN the PARENTHESES
= 1/2(8) + 1/2(-6y) + 1/5(10y) + 1/5(-25)
= 4 - 3y + 2y - 5
COMBINE the LIKE TERMS
= (-3y + 2y) + (4 - 5)
= -3y + 2y + 4 - 5
= -1y - 1
≈ -y - 1
Therefore, your answer is: -y - 1
Good luck on your assignment & enjoy your day!
