ANSWER:

Given:

  • x + y = 7
  • 3x - 2y = 11

To Find:

  • Value of x and y

Solution:

\text{We are given that,}\\\\:\longrightarrow x+y=7- - - -(1)\\\\\text{And,}\\\\:\longrightarrow 3x-2y=11- - - -(2)\\\\\text{Multiplying (1) by 2,}\\\\:\implies(x+y=7)\times2\\\\:\implies2x+2y=14- - - -(3)\\\\\text{Adding (2) and (3),}\\\\:\implies(3x+2x)+(2y\!\!\!\!\!/{\:\:}-2y\!\!\!\!\!/{\:\:})=(11+14)\\\\:\implies5x=25\\\\:\implies x=\dfrac{25\!\!\!\!\!/^{\:\:5}}{5\!\!\!/}\\\\\bf{:\implies x=5}\\\\\text{Substituting value of x in (1),}\\\\:\implies5+y=7\\\\:\implies y=7-5\\\\\bf{:\implies y=2}\\\\\text{\bf{So, value of x and y is 5 and 2 respectively.}}
