An amount of Rs 5000 is put into three investments at the rate of interest of 6%, 7% and 8% per annum. The total annual income is Rs. 358. If the combined income from the first two investments is Rs. 70 more than the income from third, find the amount of each investment by matrix method.

Prove, using properties of determinant -
=a^2(aà a^4-2ab^3)-2ab(a^3b^3-4a^2+b^2(b^4-2ba^3) =a^6-2a^3b^3+2ab(3a^2b^2)+b^6-2a^3b^3 =a^6+b^6+6a^3b^3-2a^3b^3-2a^3b^3 =a^6+b^6+2a^3b^3 =(a^3+b^3)^2...

Example 15: If x,y,z are different and Δ= | x x2 1+x3 | = 0 , then show that 1+xyz=0.
| y y2 1+y3 |
| z z2 1+z3 |
Please help me solve this question and I didn't understand what does it mean "x,y,z are different" ??
Thanks.

x + y + z = 6
x + 2z = 7
3x + y + z = 12
x + 2z = 7
3x + y + z = 12

A company produces three products everyday. Their production on a certain day is 45 tons. It is found that the production of third product exceeds the production of first product by 8 tons while the total production of first and third product twice the production of second product. Determine the production level of each product using matrix method.

2/x - 3/y + 3/z = 10
1/x + 1/y + 2/z = 10
3/x - 1/y + 2/z =13
1/x + 1/y + 2/z = 10
3/x - 1/y + 2/z =13
