Question

Solve the following pair of linear equations by the substitution method.

x + y = 14

x - y = 4


​

Answer 1

Answer:

ANSWER

x+y=14 ....(i)

x−y=4 .....(ii)

From (ii) y=x−4 ...(iii)

Substituting y from (iii) in (i), we get

x+x−4=14

⇒2x=18

⇒x=9

Substituting x=9 in (iii), we get

y=9−4=5,

i.e, y=5

x=9,y=5
