Step-by-Step Solution

To solve the equation 17x0.5+214x=27x+8.5 \frac{1}{7}x - 0.5 + \frac{2}{14}x = \frac{2}{7}x + 8.5 , we need to proceed with the following steps:

  • Step 1: Simplify the equation by combining like terms.

Examine the left-hand side (LHS):

17x+214x0.5 \frac{1}{7}x + \frac{2}{14}x - 0.5

Firstly, note that 214 \frac{2}{14} simplifies to 17 \frac{1}{7} . Therefore, the LHS becomes:

17x+17x0.5 \frac{1}{7}x + \frac{1}{7}x - 0.5 .

Combine like terms:

(17x+17x)0.5=27x0.5 \left(\frac{1}{7}x + \frac{1}{7}x\right) - 0.5 = \frac{2}{7}x - 0.5 .

  • Step 2: Compare both sides of the equation.

The right-hand side (RHS) is:

27x+8.5 \frac{2}{7}x + 8.5 .

Substitute the simplified LHS and RHS:

27x0.5=27x+8.5 \frac{2}{7}x - 0.5 = \frac{2}{7}x + 8.5 .

  • Step 3: Analyze the equation for a solution.

Subtract 27x \frac{2}{7}x from both sides:

0.5=8.5-0.5 = 8.5.

This results in a contradiction, since 0.5-0.5 does not equal 8.58.5.

  • Conclusion:

The equation does not have a solution. The coefficients of x x cancel each other out, and the remaining statement is false, indicating that no value of x x can satisfy the equation.

Therefore, the correct answer is: "No solution".

Answer

No solution
