Step-by-Step Solution

To solve this equation for x x , we will follow these steps:

  • Simplify both sides of the equation by combining like terms.
  • Rearrange the equation to isolate the variable x x .
  • Analyze the resultant equation to determine the solution.

Let's break it down:

Step 1: Simplify the left side:
The left side of the equation is 7+3x8x -7 + 3x - 8x . Combine the like terms 3x 3x and 8x-8x:
7+(3x8x)=75x -7 + (3x - 8x) = -7 - 5x

Step 2: Simplify the right side:
The right side of the equation is 9+35x 9 + 3 - 5x . Combine the constant terms 9 9 and 3 3 :
(9+3)5x=125x (9 + 3) - 5x = 12 - 5x

Step 3: Set the simplified equation:
Now the equation is:
75x=125x -7 - 5x = 12 - 5x

Step 4: Analyze the equation:
If we attempt to isolate x x by adding 5x 5x to both sides, we get:
7=12 -7 = 12

This statement is false. Since the manipulation leads to a false statement without any variable x x , the original equation has no solution.

Therefore, the equation cannot be true for any real number value of x x . Thus, the correct answer is: no solution.

Answer

No solution
