Solve the following pairs of linear equations:

Question

KnowledgeBoat · Accepted Answer

Substituting in above eq. we get, 20a + 4b = 5 .......(i) 10a - 4b = 1 .......(ii) Multiplying equation (ii) by 2 we get, 20a - 8b = 2 .......(iii) Subtracting eq. (iii) from (i) we get, ⇒ 20a + 4b - (20a - 8b) = 5 - 2 ⇒ 12b = 3 ⇒ b = . Substituting value of b in (iii) we get, ⇒ 20a - = 2 ⇒ 20a - 2 = 2 ⇒ 20a = 2 + 2 ⇒ a = ⇒ a = Hence, x = 4 and y = 5.
