Step-by-step explanation:
a. (0.60x + 0.70y)- 50 = 10
<=> 0.60x + 0.70y = 60
b. (x+y) = 5(x-y)
x+y=5x-5y
<=> 4x - 6y = 0
Answer:

Find the coordinates of c using the section formula
= = = 3
= = = 2
coordinates of c = (3, 2)
Similarly to find the coordinates of d
= = =
coordinates of d = ( , )
24542.26 is the final balance
