Answer:
<h2>The solution is x = 2 and y = 1.</h2>
Step-by-step explanation:
The given equations are x = 4 - 2y.......(1) and 3x - 2y = 4......(2).
Putting the value of the first equation in the second, we get
3x - 2y = 4
or, 3(4 - 2y) - 2y = 4
or, 12 - 6y - 2y = 4
or, 8y = 8
or, y = 1.
Putting the value of y in the first equation, we get x = 4 - 2 = 2.
