So we're trying to solve for x. To do this we need to balance the equation.
-121 -4x = 39 + 6x
Get x on one side; add 4x to both sides.
-121 = 39 + 10x
Subtract 39 from both sides (remember when subtracting a negative to a negative, it's basically just adding with negative signs).
-160 = 10x
Divide both sides by 10.
x = -16.
Hope this helps!
Let the number of months Xian and Kai will have the same number of stamps be x, then
56 + 12x = 80 + 8x
12x - 8x = 80 - 56
4x = 24
x = 24/4 = 6
Therefore, after 6 months Xian and Kai will have the same number of stamps.
turn the fraction into an improper fraction then divide and round. that will be your answer.
Answer: 0.4 pounds per person
