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
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.
