![7x+2y=17 ............................................(1)\\\\\text{ and }3x+2y=32..............................(2)/tex]When we subtract equation (2) from equation (1) , we subtract the right hand side of equation (1) from the right hand side of equation (2) and similarly for left side equation, we get[tex]7x-3x+2y-2y=17-3\\\\\Rightarrow\(7-3)x+(2-2)y=17-3 \\\\\Rightarrow\ 4x+0=14\\\\\Rightrrow\ x=\dfrac{14}{4}=\dfrac{7}{2}](/tpl/images/0019/4109/93102.png)
