Step-by-Step Solution

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

  • Step 1: Simplify both sides of the given equation.
  • Step 2: Isolate the variable x x on one side of the equation.
  • Step 3: Solve for x x .

Now, let's work through each step:

Step 1: Simplify both sides of the equation.

The original equation is 54x36x+34=39+5x18 54x - 36x + 34 = 39 + 5x - 18 .

On the left side, combine like terms: 54x36x=18x 54x - 36x = 18x .

So, the equation becomes 18x+34=39+5x18 18x + 34 = 39 + 5x - 18 .

Simplify the right side: 3918=21 39 - 18 = 21 .

This gives us 18x+34=21+5x 18x + 34 = 21 + 5x .

Step 2: Isolate the variable x x on one side.

Subtract 5x 5x from both sides to get all x x terms on one side:

18x5x+34=21 18x - 5x + 34 = 21 .

This simplifies to 13x+34=21 13x + 34 = 21 .

Subtract 34 from both sides to move constant terms to the other side:

13x=2134 13x = 21 - 34 .

This simplifies to 13x=13 13x = -13 .

Step 3: Solve for x x .

Divide both sides by 13 to solve for x x :

x=1313 x = \frac{-13}{13} .

This simplifies to x=1 x = -1 .

Therefore, the solution to the problem is x=1 x = -1 .
