1) Evaluate the algebraic expression -(5y - 3x) + 1(5y - 4) + 1(4x - 2y) - 3(-4y + 3) - (x - 2)
6x + 10y – 11
6x - 10y – 11
6x - 10y + 11
-6x + 10y – 11
1/10
Solution
Answer:
6x + 10y – 11
Explanation:
-(5y - 3x) + 1(5y - 4) + 1(4x - 2y) - 3(-4y + 3) - (x - 2)
= -5y - 3x + 5y - 4 + 4x - 2y + 12y – 9 – x + 2
= -5y + 5y - 2y + 12y + 3x + 4x – x – 4 – 9 + 2
= 6x + 10y – 11
