14x+2y=6 (1)
-7x-2y= -13 (2)
Multiply (2) by 2, we have:
-14x-4y= -26 (3)
Take (1)+(3), we can solve and get x= -1, y= 10~
4x + 6 < 3x - 5 is our given inequality
4x < 3x -11 by subtracting 6 on both sides of the inequality sign
x < -11 by subtracting 3x on both sides.
Thus, x < -11 -- choice D -- is the solution.
243.875 to the nearest tenth place is 243.9
