Evaluate algebraic expressions with a single variable Question Evaluate the following expression at x=-7. - x-5

2

Step-by-step explanation:

When x = - 7, - x - 5 = - (-7) - 5 = 7 - 5 = 2.

-12

Step-by-step explanation: Since, - x = - 7, - 7-5 = - 12 (because seven is a negative integer and the equation states that - 7 and 5 has to be subtracted, according to various expressions like - 1-1 the answer is given that it is - 2 if 7 had been a positive integer, then, 7-5=2 as when a positive and negative integer is subtracted, we give the answer either + ve or - ve influenced by the sign of the greater number) Sorry ... i just noticed that the qstn had mentioned x and not - x, but since it has to be fair in answering, i'll leave the answer as how it was ... once again sorry
