<span>Multiply equation(2) with 4 so that coefficient of become same in both the equations(You can make coefficient of y same and can follow the following procedure.) </span><span>* Subtract (3) from (1) * </span>Divide both sides by -19 *Subtract 21 from both sides. *Divide both sides by 4 so the solution is x= 3 and y= -7 Hope I helped you :)
