Answer:
(9X-31) +(4X+33)+(7X-2) = 20X
Explanation:
- To simplify the expression (9X - 31) + (4X + 33) + (7X - 2), you need to combine like terms by adding or subtracting the coefficients of the same variable (X).
- First, let's group the like terms: (9X + 4X + 7X) + (-31 + 33 - 2)
- Now, add the coefficients of X: (9X + 4X + 7X) = 20X
- And add the constants: (-31 + 33 - 2) = 0
- So, the simplified expression is: 20X + 0
- Since adding 0 doesn't change the value of an expression, you can simplify it further to just: 20X
