Cevap

5
The correct answer is 55. By distributing the fractions, combining the like terms, and properly using inverse operations to isolate xx, the equation simplifies step-by-step to x=5x = 5.

Adım Adım Çözüm

1
Distribute the fractions into the parentheses on both sides of the equation.
2x−3+3x=6x−82x - 3 + 3x = 6x - 8
Applying the distributive property removes the parentheses and prepares the equation for combining terms.
2
Combine the like terms on the left side.
5x−3=6x−85x - 3 = 6x - 8
Simplifying each side individually makes it easier to isolate the variable.
3
Subtract 5x5x from both sides to group the variable terms on the right side.
−3=x−8-3 = x - 8
Keeping the variable coefficient positive reduces the chance of a sign error.
4
Add 88 to both sides to isolate xx.
5=x5 = x
Applying the inverse operation isolates the variable and provides the final solution.
