Question

Please solve the marked sum.

Answer 1

$2x + 3y - 1 = 1......(1) \\ x - \frac{y}{2} = \frac{1}{2} \\ \frac{2x - y}{2} = \frac{1}{2} \\ 2x - y = 1..............(2) \\ putting \: (1) \: and \: (2) \: together \\ 2x + 3y - 1 = 2x - y \\ 2x - 2x + 3y + y = 1 \\ 4y = 1 \\ y = \frac{1}{4} .....................(3) \\ putting \: th e \: value \: of \: y \\ in \: equation \: (1) \\ 2x + \frac{3}{4} = 2 \\ \frac{8x + 3}{4} = 2 \\ 8x = 8 - 3 \\ x = \frac{5}{8} ....................(4)$
