Q. How many solutions does this equation have?\newline7h=7h107h = 7h - 10\newlineChoices:\newline(A)no solution\newline(B)one solution\newline(C)infinitely many solutions
  1. Analyze Equation: Analyze the equation 7h=7h107h = 7h - 10.\newlineWe start by looking at the equation and trying to simplify or rearrange it to find the value of hh.
  2. Subtract to Isolate hh: Subtract 7h7h from both sides of the equation to try to isolate hh.\newline7h7h=7h107h7h - 7h = 7h - 10 - 7h\newlineThis simplifies to:\newline0=100 = -10
  3. Evaluate Simplification: Evaluate the result of the simplification.\newlineThe equation 0=100 = -10 is a contradiction because 00 cannot equal 10-10. This means that there is no value of hh that can satisfy the equation.
  4. Conclude No Solution: Conclude the number of solutions based on the contradiction. Since we have a contradiction, the equation has no solution.
