Answer:
$300
Step-by-step explanation:
Let D = Dave's savings and S = Sam's savings.
(1) D/S = 5/4
(2) (D – 40)/(S-40) = 13/10 Multiply (1) by 4S
(3) 4D = 5S Multiply (2) by 10(S-40)
10(D - 40) = 13(S - 40) Remove parentheses
(4) 10D – 400 = 13S - 520 Solve (3) for S
S = (4/5)D Substitute into (4)
10D – 400 = 13(4/5)D - 520 Multiply each side by 5
50D – 2000 = 52D – 2600 Subtract 50D from each side
-2000 = 2D – 2600 Add 2600 to each side
600 = 2D Divide each side by 2
D = $300
Dave's savings at first were $300.
Answer:
x=8
y = 3
Step-by-step explanation:
x-y=5 and y=11-x
Substitute the second equation into the first
x - (11-x) = 5
Distribute the minus sign
x -11+x = 5
Combine like terms
2x-11 =5
Add 11 to each side
2x-11+11=5+11
2x=16
Divide by 2
2x/2 = 16/2
x=8
Now find y
y=11-x
y=11-8
y=3
