Question

99+450:к=10860*а+40=800:2​

Answer 1

$1)99 + 450 \div k = 108 \\ 450 \div k = 108 - 99 \\ 450 \div k = 9 \\ k = 450 \div 9 \\ k = 50 \\ 2)60 \times a + 40 = 800 \div 2 \\ 60a + 40 = 400 \\ 60a = 400 - 40 \\ 60a = 360 \\ a = 360 \div 60 \\ a = 6$

Answer 2

To solve the equation system you've provided, we have:

1. $99 + 450k = 10860a + 40$
2. $800 = 2k$

Let's solve for the variables $k$ and $a$:

From equation (2), we can solve for $k$: $800 = 2k \Rightarrow k = \frac{800}{2} = 400$

Now we can substitute this value of $k$ into equation (1) and solve for $a$: $99 + 450k = 10860a + 40$ $99 + 450(400) = 10860a + 40$ $99 + 180000 = 10860a + 40$ $180099 = 10860a + 40$ $180059 = 10860a$ $a = \frac{180059}{10860} \approx 16.591$

So, the solutions for the variables are $k = 400$ and $a \approx 16.591$.
