Answer:
-1/2 and 13/2
Step-by-step explanation:
Replace x and y in the equation with what they tell you x and y equal.
2(14) / 13 - 9(1/3)
Now simplify:
2 x 14 = 28
9 x 1/3 = 3
You now have:
28/13-3
Simplify again to het 28/10 this can be reduced to 14/5
Step-by-step explanation:
Let the total amount of salary be X, then
3/10X + 2/3X + amount left= his salary(X)
(9X + 20X)/ 30 + 2100 = X
29X/30 - X = -2100
(29X - 30X)/30 = -2100
by cross multiplying
-X = -2100×39
-X = -81900
divide both side by -1
X = 81900.
therefore his salary = 81900
