⇒3x+xy−4y−12 = 17 3(x−4)+y(x−4) = 17 (x−4)(y+3) = 17 (i) for x−4=1 ⇒y+3 = 17 (5,14) (ii) for x−4=−1⇒y+3=−17 (3,−20) (iii) for x−3 = 17 ⇒y+3 = 1 (20,−2) (iv)for x−3=−17⇒y+3=−1 (−14, −4)
⇒3x+xy−4y−12=173(x−4)+y(x−4)=17(x−4)(y+3)=17(i)forx−4=1⇒y+3=17(5,14)(ii)forx−4=−1⇒y+3=−17(3,−20)(iii)forx−3=17⇒y+3=1(20,−2)(iv)forx−3=−17⇒y+3=−1(−14,−4)
