Question

KnowledgeBoat · Accepted Answer

Substitute in above equations, ........(i) ........(ii) Multiplying (i) by and (ii) by we get, .......(iii) .......(iv) Adding (iii) and (iv) we get, Substituting value of p in (i) we get, Subtracting (vi) from (v) we get, ⇒ x + 2y - (2y - 3x) = 3 - 1 ⇒ x + 3x = 2 ⇒ 4x = 2 ⇒ x = . Substituting value of x from (v) we get, Hence, x =
