Answer:
-6
Step-by-step explanation:
-4 + (-2)
recall that;
- * - = +
- * + = -
+ * - = -
+ * + = +
So when we expand we'll have
-4 ( + * -) *2
-4 - 2 = -6
By 4 becuase this will change the -4y to -16y , then adding the 2 equations will eliminate y.

Answer:
Total number of flat screen sold is 3/4
Step-by-step explanation:
Let the total number of the flat screen sold be y
y = number of flat screen sold in the morning + number of the flat screen sold in the afternoon.
Number sold in the morning = 5/15
Number sold in the afternoon = 1/3
Y = 5/12 + 1/3
Find the LCM of 12 and 3
Y = (5 + 4)/12
Y = 9/12
Y = 3/4
Total number of flat screen sold is 3/4
