Answer:
The value of x , y using substitution method is 2 , 5
Step-by-step explanation:
Given as :
The two linear equation as
6 y - 4 x = 22 .......1
y + 2 x = 9
Let y = 9 - 2 x .......2
Now, using substitution method
Substitute the value of y from eq 2 into eq 1
i.e 6 × (9 - 2 x) - 4 x = 22
Or, 54 - 12 x - 4 x = 22
Or, 12 x + 4 x = 54 - 22
Or, 16 x = 32
∴ x =
i.e x = 2
Now, Put the value of x into eq 2
∴ y = 9 - 2 x
So, y = 9 - 2 × 2
Or, y = 9 - 4
i.e y = 5
So, The value of x , y = 2 , 5
Hence, The value of x , y using substitution method is 2 , 5 Answer
