Question

Solve by substitution method : 11x-8y = 24 , 3x+5y = -7

Answer 1

11x-8y=24__(I) 3x+5y=-7__(ii) From equation (ii) ,we get 3x= -7-5y x=-7-5y/3 Putting the value of x in equation (I) we get 8y=11x-24 8y=-77-55y/3 y=-77-55y/24 24y=-77-55y 79y=-77 y=-77/79 Find x by putting the value of y in any of the equations. Do let me know whether I was right or wrong.
