In each row, decide whether the expression in column A is equivalent to the expression in column B. If they are not equivalent, show how to change one expression to make them equivalent. A B
1. 3x - 2x + 0.5x 1. 1.5x
2. 3(x + 4) - 2(x + 4) 2. x + 3
3. 6(x + 4) - 2(x + 5) 3. 2(2x + 7)
4. 3(x + 4) - 2(x + 4) + 0.5(x + 4) 4. 1.5
5. 20() 5. (16x + 30y - 20)

Show how to change one expression to make A2 and B2 equivalent.
