Step-by-step solution

To solve the given linear equation 31+48x+46=83x85+15x -31 + 48x + 46 = 83x - 85 + 15x , we'll follow these steps:

  • Step 1: Simplify both sides by combining like terms.
  • Step 2: Move all x x -terms to one side and constant terms to the other.
  • Step 3: Solve for x x .

Now, let's work through each step:

Step 1: Simplify both sides of the equation:
On the left side, combine like terms: 31+46=15 -31 + 46 = 15 . Thus, the left side becomes 15+48x 15 + 48x .
On the right side, combine the x x -terms: 83x+15x=98x 83x + 15x = 98x . The right side becomes 98x85 98x - 85 .

The equation now reads: 15+48x=98x85 15 + 48x = 98x - 85 .

Step 2: Move all x x -terms to one side and constant terms to the other:
Subtract 48x 48x from both sides: 15=98x48x85 15 = 98x - 48x - 85 .
Simplify the x x -terms: 98x48x=50x 98x - 48x = 50x . Thus, 15=50x85 15 = 50x - 85 .

Add 85 to both sides: 15+85=50x 15 + 85 = 50x , resulting in 100=50x 100 = 50x .

Step 3: Solve for x x by dividing both sides by 50:
x=10050=2 x = \frac{100}{50} = 2 .

Therefore, the solution to the problem is x=2 x = 2 .
