Given : The pair of equations x=2 and y = -3
To Find : Correct option:
a) no solution
b) one solution
c) infinitely many solutions
d) two solutions
Solution:
pair of equations x =2 and y = -3
x =2 can be written as
x + 0.y = 2 ... Eq1
y = -3 can be written as
0.x + y = -3 Eq2
0.Eq1 + Eq2
=> 0 + 0 + 0 + y = 0 - 3
=> y = - 3
0 * Eq2 + Eq1
=> 0 + 0 + x + 0 = 0 + 2
=> x = 2
Hence x = 2 and y = -3 is the solution
There is only one solution x = 2 and y = - 3
Correct option is option b) One Solution
