Answer:
3) ab = ba
This is called Commutative property of Multiplication.
4) 5 (3x -2) = 5*(3x) - 5*(2) = 15x -10
This is called Distributive property.
5) 1/2 (4-2x) = 2 - 2x
Applying distributive property on left side
1/2(4) - 1/2 (2x) = 2- 2x
2-x ≠ 2 - 2x
The pair of equation is not equivalent.
6) 1/2 (6x -2) = 3 - x
Applying distributive property on left side
1/2 (6x) - 1/2 (2) = 3 - x
3x - 1 ≠ 3 - x
The pair of equation is not equivalent.
7) 32y +12y = 44y
8) 12+ 3x - x - 12 = 12-12+3x -x = 2x
