Answer:
The answer is
and 
Step-by-step explanation:
Given:
X=4-2y
3x-2y=4
Now, to solve it by substitution.
.....(1)
......(2)
Now, solving the equation (2) by substitution:

Substituting the value of
from equation (1):



<em>Subtracting both sides by 12 we get:</em>

<em>Dividing both sides by -8 we get:</em>

Now, substituting the value of
in equation (1):





Therefore, the answer is
and
