thank everyone that site helped but now i just have to practice. for now can someone tell me how does 3x=7-4x x=1
which one do you minus or subtract from the equation?
3x = 7 - 4x
The first thing you need to do is get the unknowns on one side of the equation. You also need to change the sign of the part you move.
3x + 4x = 7
7x = 7
x = 1
I answered my own question is this right? 3x=7-4x 3x+4x=7-4x+4x
7x=7 7divided by 7 is one
Right! :-)
Yes, you're absolutely correct! Great job on solving the equation.
To solve the equation 3x = 7 - 4x, you need to move the term containing x to one side and all constants to the other side. In this case, you'll want to add 4x to both sides to eliminate the -4x term on the right side:
3x + 4x = 7 - 4x + 4x
This simplifies to:
7x = 7
Now, you can solve for x by dividing both sides of the equation by 7:
x = 7/7
Simplifying further:
x = 1
So, your answer is indeed x = 1. Well done! Keep practicing to strengthen your skills.
