Q. Find the truth set of the following simultaneous equation\newline5x634\frac{5x}{6}-\frac{3}{4} y=12×23y=\frac{1}{2}\times\frac{2}{3} y=52y=\frac{5}{2}
  1. Simplify Equations: Simplify the equations:\newlineFirst equation: (5x634y=12)(\frac{5x}{6} - \frac{3}{4} y = \frac{1}{2})\newlineSecond equation: (23y=52)(\frac{2}{3} y = \frac{5}{2})
  2. Solve for y: Solve the second equation for y:\newline23y=52\frac{2}{3} y = \frac{5}{2}\newlineMultiply both sides by 32\frac{3}{2} to isolate y:\newliney=(52)×(32)=154y = \left(\frac{5}{2}\right) \times \left(\frac{3}{2}\right) = \frac{15}{4}
  3. Substitute y into First Equation: Substitute y=154y = \frac{15}{4} into the first equation:\newline5x634×154=12\frac{5x}{6} - \frac{3}{4} \times \frac{15}{4} = \frac{1}{2}\newline5x64516=12\frac{5x}{6} - \frac{45}{16} = \frac{1}{2}
  4. Solve for x: Solve for x:\newlineFirst, convert 12\frac{1}{2} to a fraction with a denominator of 1616:\newline12=816\frac{1}{2} = \frac{8}{16}\newlineNow, add 4516\frac{45}{16} to both sides:\newline5x6=816+4516\frac{5x}{6} = \frac{8}{16} + \frac{45}{16}\newline5x6=5316\frac{5x}{6} = \frac{53}{16}\newlineMultiply both sides by 65\frac{6}{5} to solve for x:\newlinex=531665=31880x = \frac{53}{16} \cdot \frac{6}{5} = \frac{318}{80}\newlineSimplify x:\newlinex=15940x = \frac{159}{40}
