Answer:
Trapezoid
Step-by-step explanation:
So there's four sides on a trapezoid. The top and bottom ones are parallel. But they're not congruent. I don't think... Anyway, good luck.
I guess the number 2 is to indicate the question...
Then the equation would be 1/3 - 1/2x = -2/3
1/3 - 1/2x - 1/3 = -2/3 - 1/3
-1/2x = -3/3
-1/2x = -1
-1/2x *2 = - 1*2
-x = -2
-x * -1 = -2 * -1
x = 2
Good luck
