The solution set of 4x-3y = 10 and 3x + y = 14 is
Equation 1Â :Â 4x - 3y = 10
Equation 2Â : 3x + y = 14
Multiplying equation (ii) by 3 and adding it to equation (i)
=> $$(4x+9x)+(-3y+3y)=(10+42)$$
=> $$13x=52$$
=> $$x = \frac{52}{13}=4$$
Substituting it in equation (ii), => $$y=14-3(4) = 14 - 12 = 2$$
$$\therefore (x,y)=(4,2)$$
=> Ans - (B)
