1/2 because everything lose half its value points wise.
Here is the work:
(13x - 5x) + 12 - 2y = 6
(8x) + 12 - 2y = 6
-2y = -8x - 12 + 6
-2y = -8x - 6
y = 4x + 3
Answer: 48
Step-by-step explanation: if i did the math correct 1/3 times the base (9) times 16 is 48. the formula is 1/3 x Bh
-2(x + 3) = -2(x + 1)
-2x - 6 = -2x - 2
-2x + 2x = -2 + 6
0 = 4
Therefore, the system has no solution.
