Understand the problem

Solve for X:

364x+357819x=168+455x3819 \frac{36}{4}x+\frac{35}{7}-\frac{81}{9}x=\frac{16}{8}+\frac{45}{5}x-\frac{38}{19}

Step-by-step solution

To solve the problem, we'll follow these steps:

  • Step 1: Simplify each fraction in the equation.
  • Step 2: Combine like terms involving x x on one side of the equation and constants on the other.
  • Step 3: Solve the simplified equation for x x .

Let's work through each step together:

Step 1: Simplify each fraction:

  • 364=9\frac{36}{4} = 9,
  • 357=5\frac{35}{7} = 5,
  • 819=9\frac{81}{9} = 9,
  • 168=2\frac{16}{8} = 2,
  • 455=9\frac{45}{5} = 9,
  • 3819=2\frac{38}{19} = 2.

With these simplifications, our equation becomes:

9x+59x=2+9x2 9x + 5 - 9x = 2 + 9x - 2 .

Step 2: Combine like terms.

  • The terms 9x 9x and 9x-9x cancel out on the left, so we have:
  • 5=2+9x2 5 = 2 + 9x - 2 .
  • Simplify the right side: 5=9x 5 = 9x .

Step 3: Solve for x x :

5=9x 5 = 9x

Divide both sides by 9 9 :

x=59 x = \frac{5}{9} .

Therefore, the solution to the equation is x=59 x = \frac{5}{9} .

Final Answer

59 \frac{5}{9}

Key Points to Remember

Essential concepts to master this topic
  • Simplify First: Reduce fractions like 36/4 = 9 before solving
  • Combine Terms: Group x-terms: 9x - 9x + 9x = 9x
  • Verify Solution: Substitute x = 5/9 back into original equation ✓

Common Mistakes

Avoid these frequent errors
  • Forgetting to simplify fractions before solving
    Don't leave 36/4x as is and work with complex fractions = messy calculations and errors! This makes combining terms harder and increases mistakes. Always simplify fractions like 36/4 = 9 first to make the equation cleaner.

FAQ

Everything you need to know about this question

Do I have to simplify the fractions first?

+

Yes, absolutely! Simplifying fractions like 364=9 \frac{36}{4} = 9 makes the equation much cleaner and easier to work with. It prevents calculation errors.

Why did the 9x terms cancel out on the left side?

+

Because we had 9x9x 9x - 9x , which equals zero! When you have the same coefficient with opposite signs, they cancel each other out completely.

How do I know which terms to move to which side?

+

Move all x-terms to one side and all constants to the other side. In this problem, we ended up with constants on the left (5) and x-terms on the right (9x).

What if I get a different answer when I substitute back?

+

That means there's an error in your work! Go back and check your fraction simplifications and combining like terms. Double-check each arithmetic step.

Is 5/9 the simplest form of my answer?

+

Yes! Since 5 and 9 have no common factors other than 1, 59 \frac{5}{9} is already in lowest terms.
