Step-by-Step Solution

To solve this equation, we'll proceed as follows:

  • Step 1: Simplify both sides of the equation by combining like terms.
  • Step 2: Move all terms with x x to one side of the equation.
  • Step 3: Isolate the variable x x and solve for it.

Now, let's follow these steps in detail:

Step 1: Simplify each side of the equation by combining like terms.

Left side: 36x52+8x 36x - 52 + 8x simplifies to (36x+8x)52=44x52 (36x + 8x) - 52 = 44x - 52 .

Right side: 19x+5431 19x + 54 - 31 simplifies to 19x+(5431)=19x+23 19x + (54 - 31) = 19x + 23 .

Thus, the equation becomes:

44x52=19x+23 44x - 52 = 19x + 23

Step 2: Move all x x terms to one side.

Subtract 19x 19x from both sides:

44x19x52=23 44x - 19x - 52 = 23

This simplifies to:

25x52=23 25x - 52 = 23

Step 3: Isolate the variable x x .

Add 52 to both sides:

25x=23+52 25x = 23 + 52

This gives 25x=75 25x = 75 .

Finally, divide both sides by 25:

x=7525 x = \frac{75}{25}

Thus, x=3 x = 3 .

Therefore, the solution to the problem is x=3 x = 3 , which corresponds to choice 2.
