Question

What is the value of 3x when 2x + 3 =3x - 4

Answer 1

Answer:

3x=21

Step-by-step explanation

2x + 3 = 3x - 4

-2x from both sides, you get

3 = x - 4

Add 4 to both sides and you get

7 = x

3x would be 3×7 which would be 21

Answer 2

Answer:

Possibly 21.

Step-by-step explanation:

You take the equation (2x+3=3x-4), subtract 2x from 3x, and get x. Then you add 4 to 3 and get 7. x=7; now you take 3 and times that with x (7) and will get 21.
