Question

The solution for the pair of linear equations

x + 2y = 5 and 7x + 3y = 13 is (2, 1).

• A. True
• B. False

Answer 1

The correct option is B

False

x + 2y = 5,....(i)

7x + 3y = 13....(ii)

From (i) x = 5 - 2y

Substituting x in (ii) we get
7(5 - 2y) + 3y = 13

$\Rightarrow$ -11y = - 22

$\Rightarrow$ y = 2

Substituting the value of y in (i) we get

x = 5 - 2(2)

$\Rightarrow$ x = 1
Hence, the solution is (1, 2).
