Answer: x = 3
Step-by-step explanation:
When the base is the same, the exponents are the same:
3-2x = -x
solve fore x
add 2x to both sides
3-2x = -x
+2x +2x
x = 3

9 3
</span><span>You need to add both distances
</span><span>
|-9| + 3 = 9 + 3 = 12
</span><span>half
</span><span>12 : 2 = 6
</span><span>Now , we measure the distance towards the center section
</span><span>1 way
-9 + 6 = -3
2 way
3 - 6 = -3
Answere : -3
