himpunan penyelesaian y+x=62x-y+z=4adalah{(x,y,z)}.nilai x+z adalah ​

100 = number of sets of clubs manufactured per month S = sell-price for a set of clubs
Expenses per month = 23,250 + 145(100) = 37,750
Revenue per month = 100 S
Break-even when Expenses = Revenue
100 S = 37,750
One question: How did you solve it without an equation ?

To calculate the break-even price per set of golf clubs, we first determine total costs, which amount to $37,750. We then equate revenue to total costs and solve for the price per set, resulting in a break-even price of $377.50. This price is necessary to cover all fixed and variable costs associated with producing 100 sets of golf clubs.

Penjelasan dengan langkah-langkah:Diberikan sistem persamaan:y + x = 62x - y + z = 4Kita diminta mencari nilai x + z dalam himpunan penyelesaian {(x, y, z)}Langkah penyelesaian:Dari persamaan (1):y = 6 - xSubstitusikan y ke persamaan (2):2x - (6 - x) + z = 42x - 6 + x + z = 43x - 6 + z = 4z = 4 + 6 - 3xz = 10 - 3xSekarang, nilai x + z = x + (10 - 3x) = 10 - 2xJadi, nilai x + z = 10 - 2x, tergantung nilai x.Artinya, himpunan penyelesaiannya adalah:{(x, y, z) | y = 6 - x, z = 10 - 3x}Jika ingin nilai x + z spesifik, harus diketahui nilai x terlebih dahulu.
