The correct question is:

Solve  2x + 3y = 5 and 5x - 2y = 4 by substitution method.

Solution:

Given,

      2x + 3y = 5 ................1

and 5x - 2y = 4 ...........2

From equation 1,

      3y = 5 - 2x

=> y = (5 - 2x)/3 ...........3

Put value of y in equation 2, we get

      {15x - 2(5 - 2x)}/3 = 4

=> 15x - 2(5 - 2x) = 4*3

=> 15x - 10 - 4x = 12

=> 11x - 10 = 12

=> 11x = 10 + 12

=> 11x = 22

=> x = 22/11

=> x = 2

From equation 3,

      y = (5 - 2*2)/3

=> y = (5 - 4)/3

=> y = 1/3

So, x = 2 and y = 1/3
