You can use elimination by adding the two equations to "cancel out" one of the variables. in this example y will cancel out.
2x + y = 3
+
2x - y = 4
________
2x = 6
x = 3
now that we know our x value, we can plug it into one of the other equations to get our y value.
2(3) + y = 3
6 + y = 3
y = -3
your answer for this system is x=3, y=-3
Graph it like you would a normal equation except if it's not "equal to" it's a dashed line instead of solid line. Then shade the appropriate area on the graph,
for example..
y > 2x +1
is graphed as a dashed line y = 2x +1 since it doesn't actually equal y.
y is greater than the line/equation so the area above is shaded where y is bigger
Answer:
But this condition is not feasible so, from given equation the value of D is not determine
Step-by-step explanation:
Given equation is :
= 22 - 3
Or, 
= 18
Or 0 = 18
But 0 ≠ 18
but this condition is not feasible so, from given equation the value of D is not determine .. Answer
