Answer:
y = 15 and x = 22
Step-by-step explanation:
700 = 25x + 10y
x = y + 7
700 = 25(y +7) + 10y
700 = 35y + 175
525 = 35y
15 = y
700 = 25x + 150
550 = 25x
22 = x
First, use distributive property on the right half.
2 * 5 = 10
2 * 2n = 4n
4n - 9 = 10 + 4n
Add 9 to both sides
4n = 19 + 4n
Subtract 4n from both sides
0 = 19
But thats not true. Therefore, there is no solution.
Answer: 9 (7 + 9)
63 = 9 * 7 and 81 = 9 * 9
