Question

Simplify:
2. 4x - (3y - x + 2z)
1. a.- (b-2a)
3. (a? 4 b2 + 2ab) - (a? + b2 - 2ab)
5. -4x2 + {(2x? = 3) - (4 - 3x?)}
7. a - 2b - {3a - (2b - 3c)}]
8, -x + (5y - {x - (5y - 2x)}]
4. -3(a + b) + 4(2a - 3b) - (2a - b)
6. -2(x -y + xy) - 3(x + y - xy)​

Answer 1

I'm only solving Question 1 like this only u have to solve the rest:-

4x - (3y - x + 2z)

sign will change I hope that u already know the reason

=> 12y + 4x - 8z

this will only the answer!
