Question

Write whether the following pair of linear equation is consistent or not x + y = 14, x – y = 4​

Answer 1

Step-by-step explanation:

The pair of linear equations in two variables:

x+y=14

x-y=4.

are consistent.

By substitution method:

x-y=4

x=4+y

Substituting x in another equation, we get:

4+y+y=14

2y=14-4=10

y=10/2=5.

now by substituting y in x=4+y:

x=4+5=9.
