Solve for X:
To solve the equation , follow these steps:
1. Subtract from both sides to get:
2. Simplify the equation:
3. Add to both sides:
4. Divide both sides by :
4
\( x+7=14 \)
\( x=\text{?} \)
You want to isolate x by getting all x-terms on one side. Since 7x is bigger than 4x, subtract 4x from both sides to get on the left and eliminate x from the right side.
That works too! You could add 3 to both sides first, then subtract 4x. The important thing is to keep the equation balanced - whatever you do to one side, do to the other.
Choose the side with the larger coefficient! Since 7x > 4x, keep the x terms on the left side. This avoids negative coefficients and makes the math easier.
Isolating x means getting x by itself on one side of the equation. You'll have [some number] when you're done solving.
Yes! You can also work backwards: if x = 4, then the left side is 7(4) - 3 = 28 - 3 = 25, and the right side is 4(4) + 9 = 16 + 9 = 25. Both sides equal 25, so x = 4 is correct!
