Question

The balanced scale represents the equation: 3x + 1 - 2x + 4

Answer 1

Answer:

B

Step-by-step explanation:

the equal is correctly

3x + 1 = 2x + 4

what was done now :

2 x-blocks (2x) subtracted from the right side, and 1 numbered block subtracted from the left side.

to reestablish balance and equality of both sides, we need to do more the exact same things - just in the other sides.

2 x-blocks subtracted from the LEFT side, and 1 numbered block subtracted from the RIGHT side.

and that is answer B.
