Step-by-Step Solution

To solve the linear equation 8.51x+3.46.14x=7.51+3.8x6.1 8.51x + 3.4 - 6.14x = 7.51 + 3.8x - 6.1 , we will proceed with these steps:

  • Step 1: Combine like terms on the left side.
  • Step 2: Combine like terms on the right side.
  • Step 3: Isolate x x by collecting all x x terms on one side of the equation.
  • Step 4: Solve for x x .

Now, let's work through these steps in detail:

Step 1: Combining like terms on the left side:
The left side of the equation is 8.51x+3.46.14x 8.51x + 3.4 - 6.14x .
Combine the x x -terms: (8.516.14)x+3.4=2.37x+3.4(8.51 - 6.14)x + 3.4 = 2.37x + 3.4.
The left side simplifies to 2.37x+3.4 2.37x + 3.4 .

Step 2: Combining like terms on the right side:
The right side of the equation is 7.51+3.8x6.1 7.51 + 3.8x - 6.1 .
Combine the constant terms: 7.516.1=1.41 7.51 - 6.1 = 1.41 .
The right side simplifies to 3.8x+1.41 3.8x + 1.41 .

Step 3: Isolate x x :
Start with the equation 2.37x+3.4=3.8x+1.41 2.37x + 3.4 = 3.8x + 1.41 .
Subtract 2.37x 2.37x from both sides to have 3.4=(3.82.37)x+1.41 3.4 = (3.8 - 2.37)x + 1.41 .
This simplifies to 3.4=1.43x+1.41 3.4 = 1.43x + 1.41 .

Subtract 1.41 from both sides to isolate the term with x x :
3.41.41=1.43x 3.4 - 1.41 = 1.43x , resulting in 1.99=1.43x 1.99 = 1.43x .

Step 4: Solve for x x :
Divide both sides by 1.43 1.43 :
x=1.991.431.39 x = \frac{1.99}{1.43} \approx 1.39 .

Therefore, the solution to the equation is x=1.39 x = 1.39 .

Answer

1.39 1.39
