Step-by-Step Solution

Let's solve the given equation 8.15x13.14+5=7.18.4x 8.15x - 13.14 + 5 = 7.1 - 8.4x step by step:

Step 1: Simplify both sides of the equation.
On the left-hand side, combine like terms:

8.15x13.14+5=8.15x8.14 8.15x - 13.14 + 5 = 8.15x - 8.14

Step 2: Simplify the right-hand side:

7.18.4x 7.1 - 8.4x (no combining needed here).

Now the equation is:

8.15x8.14=7.18.4x 8.15x - 8.14 = 7.1 - 8.4x

Step 3: Move all x x -terms to one side and constant terms to the other side.
Add 8.4x 8.4x to both sides:

8.15x+8.4x8.14=7.1 8.15x + 8.4x - 8.14 = 7.1

16.55x8.14=7.1 16.55x - 8.14 = 7.1

Step 4: Move the constant term on the left to the right side by adding 8.14:

16.55x=7.1+8.14 16.55x = 7.1 + 8.14

16.55x=15.24 16.55x = 15.24

Step 5: Solve for x x by dividing both sides by 16.55:

x=15.2416.55 x = \frac{15.24}{16.55}

x0.92 x \approx 0.92

Therefore, the solution to the equation is x=0.92 x = 0.92 .

Answer

0.92 0.92
