    Here your answer goes Step :-1 Take one equation from the two equations and represent it in the form of x and y by replacing 7x - 15y = 2----- > 1 x + 2y = 3------- > 2 Take equation 2 x = 3 - 2y ------>> 3 Step :- 2 Now , Substitute the value of x in equation 1 7 ( 3 - 2y ) - 15 = 2 21 - 14y - 15y = 2 21 - 29y = 2 -29y = 21 - 2 y = 29/19 ​ Step :- 3 Put the obtained value of y in equation 3 x = 3 - 2yx=3−2y x = 29/49 Hope you like this answer ​

    2Thank You
