Solve the following simultaneous linear equations: 2x - (3/4)y = 3 5x - 2y = 7

Question

KnowledgeBoat · Accepted Answer

Given, 2x - = 3 .........(i) 5x - 2y = 7 ..........(ii) Multiplying eq. (i) by 5 and (ii) by 2 we get, 10x - = 15 .......(iii) 10x - 4y = 14 ........(iv) Subtracting eq. (iv) from (iii), Substituting value of y in eq. (ii) we get, ⇒ 5x - 2(4) = 7 ⇒ 5x - 8 = 7 ⇒ 5x = 15 ⇒ x = 3. Hence, x = 3 and y = 4.
