Answer:
The answer is 7x
Step-by-step explanation:
To solve the problem drop the brackets and add the like terms
∵ (4x - 6) + (3x + 6)
- There is no number multiplied by each bracket so drop the
brackets without any change in the values inside them
∴ (4x - 6) + (3x + 6) = 4x - 6 + 3x + 6
- The terms 4x and 3x are like terms, so add them
∵ 4x + 3x = 7x
- The terms -6 and 6 are like terms, so add them
∵ -6 + 6 = 0
∴ 4x - 6 + 3x + 6 = (4x + 3x) + (-6 + 6)
∵ (4x + 3x) + (-6 + 6) = 7x + 0
∴ 4x - 6 + 3x + 6 = 7x
∴ (4x - 6) + (3x + 6) = 7x
The answer is 7x
