Step-by-Step Solution

To solve this linear equation, we'll follow these steps:

  • Step 1: Combine like terms on each side of the equation.
  • Step 2: Move all terms involving x x to one side of the equation.
  • Step 3: Isolate the variable x x to solve for it.

Let's work through each step:

Step 1: Simplify both sides of the equation.
On the left side, combine like terms: 7.11.14+3.18x=5.96+3.18x 7.1 - 1.14 + 3.18x = 5.96 + 3.18x .
On the right side, combine like terms involving x x and constant terms: 9.14x+3.5x+1.9=12.64x+1.9 9.14x + 3.5x + 1.9 = 12.64x + 1.9 .

Step 2: Rearrange to move all x x terms to one side.
We start with the simplified equation: 5.96+3.18x=12.64x+1.9 5.96 + 3.18x = 12.64x + 1.9 .
Subtract 3.18x 3.18x from both sides to get: 5.96=12.64x3.18x+1.9 5.96 = 12.64x - 3.18x + 1.9 .

This simplifies to 5.96=9.46x+1.9 5.96 = 9.46x + 1.9 .

Step 3: Isolate x x by performing arithmetic operations.
Subtract 1.9 from both sides: 5.961.9=9.46x 5.96 - 1.9 = 9.46x .
This gives us 4.06=9.46x 4.06 = 9.46x .

Finally, divide both sides by 9.46 to solve for x x :
x=4.069.460.42 x = \frac{4.06}{9.46} \approx 0.42 .

Therefore, the solution to the problem is x=0.42 x = 0.42 .

Answer

0.42 0.42
