Answer:
x=3, y=9
Explanation:
Let 7x-2y=3 be eqn i
Let 4x-2y= -6 be eqn ii
We solve silmutaneously using elimination method
Eliminate -2y by subtracting eqn ii from i
Therefore,
7x-4x + (-2y-(-2y)) = 3-(-6)
3x+ (-2y+2y) = 3+6
3x+0=9
3x=9
x=9/3
x=3
Substitute x=3 into eqn i
7(3) - 2y = 3
21 - 2y = 3
-2y = 3 - 21
-2y = -18
y= -18/-2
y=9
Therefore, x=3 and y=9
