Answer:
-x
Step-by-step explanation:
Note that when there is a standalone variable (such as the x in this example), it typically actually means 1x. (If it is -x, it will be -1x.) However, you do not write 1 in front, as it is presumed.
Subtract the coefficient of each terms:
1x - 2x = -1x
-x is your simplified form.
Answer is -x
• If a term doesn’t have a coefficient is considered that the coefficient is 1
-2x + 1x
• collect like terms by calculating the sum of the coefficients
(-2 + 1)x
• Write the sum
-1x
• The coefficient negativeone doesn’t have to be written but the sign remains
-x
