Question

In the following activity, match each pair of equivalent expressions.

1. 2(x - 2)
-3x + 6 + 4x
2. (x + 14) - (8 - 2x)
9x - 2(3x - 3)
3. 3(x + 5)
(7 - 2x) + (3x - 11)
4. -4(x + 1) + 5x
-7 + 6x - 4x + 3
5. (7 + 5x) + (-4x - 1)
-2x + 9 + 5x + 6

Answer 1

In this activity, we need to match each pair of equivalent expressions.

Step-by-step explanation:

1. 2(x - 2) = -3x + 6 + 4x
2. (x + 14) - (8 - 2x) = 9x - 2(3x - 3)
3. 3(x + 5) = (7 - 2x) + (3x - 11)
4. -4(x + 1) + 5x = -7 + 6x - 4x + 3
5. (7 + 5x) + (-4x - 1) = -2x + 9 + 5x + 6
