Answer» 3x+5y = 25 , 7x+6y = 30Using substitution method :3x+5y = 25 --------> (i)7x+ 6y = 30 -------->(ii) From equation(i)3x= 25-5y x = 25-5y/ 3------->(iii) Putting the value of x in equation (ii)7x +6y =307(25-5y/3) = 30175 -35y +18y = 90175 -90 -17y =085 -17y =0-17y = -85y = 85/ 17y = 5 Putting value of y in equation (iii)x= 25-5y /3x= 25-5(5)/ 3 x= 25-25 / 3x= 0/3x = 0 So value of x= 0 and y= 5 Like my answer if you find it useful! |
