Solve the following pair of linear equations by elimination method:

4x — 19y + 13 = 0, 13x — 23y = —19

multiplying first equation by 13 and second equation by 4 to get same coefficient of x.

we get, 52x – 247 y = –169 …[1]


52x – 92y = –76 …[2]


eq[2] – eq[1]


155y = 93


⇒


Put this result in 4x — 19y + 13 = 0 to find the value of x


4x — 19() + 13 = 0


⇒ x =
