Answer:
J. x = 1
Step-by-step explanation:
Write an equation based on the image of the scales.
3x + 6 = 9
Subtract 6.
3x = 3
Divide by 3.
x = 1
If you haven't learned to solve equations yet, the same thought process can be used with the scale image. The scales are balanced. To keep them balanced, remove 6 of the pieces marked "1" from BOTH sides of the scale. Then the scale will have three x's on one side and three "1"'s on the other side. So each x has to be one "1".
