Q. Solve for x \mathrm{x} .\newline21x=−72 \frac{21}{x}=-\frac{7}{2} \newlineAnswer:
  1. Identify Equation: Identify the equation to solve.\newlineWe have the equation 21x=−72\frac{21}{x} = -\frac{7}{2}. We need to find the value of xx that satisfies this equation.
  2. Multiply by xx: Multiply both sides of the equation by xx to eliminate the denominator on the left side.\newline21x×x=−72×x\frac{21}{x} \times x = -\frac{7}{2} \times x\newline21=−7x221 = -\frac{7x}{2}
  3. Multiply by 22: Multiply both sides of the equation by 22 to eliminate the fraction on the right side.\newline21×2=(−7x2)×221 \times 2 = \left(-\frac{7x}{2}\right) \times 2\newline42=−7x42 = -7x
  4. Divide by −7-7: Divide both sides of the equation by −7-7 to solve for x.\newline42−7=−7x−7\frac{42}{-7} = \frac{-7x}{-7}\newline−6=x-6 = x
