Answer:
x = 9
Step-by-step explanation:
-x = 17 - 26 Take the numbers to one side and leave the letters on the other side
-x = -9 Subtract the numbers
x = 9 since the x and the 9 are negative they become positive
(two negatives equals a positive only when multiplying or
dividing and in this case you are dividing the -1x to both
sides)
