Answer 1

Answer:

a) c

b) 4x - 5y

c) 12 - 40x

Step-by-step explanation:

a) c - d + (c - d) - c

=> c - d + c - d - c

=> c + c - c - d - d

=> c ← Answer

b) x - ( x - y ) - y - ( y - x ) + 3x - 4y

=> x - x + y - y - y + x + 3x - 4y

=> 4x - 5y ← Answer

c) 7 - 82x + 5 + 11x + 31x

=> 12 - 82x + 42x

=> 12 - 40x ← Answer
