Combine Like Terms

- (x + 3) - (x - 4)

-2x+1

Step-by-step explanation:

Given the difference of Functions

- (x + 3) - (x - 4),

To combine both functions, first we need to use the mathematical signs to open the brackets. This will give us;

-x-3-x+4

Note that - * - = +

and also - * + = -

Step 2:

Collecting the like terms

-x+3-x+4

= (-x-x) - 3+4

= - 2x+1

The combined term results to - 2x+1

Answer: - 2x + 1

Step-by-step explanation: Use the distributive property and combine terms.
