Answer 2

Ответ:

450-x=60*7

450-x=420

x=450-420

X=30

480/x=100/10

480/X=10

x=480/10

x=48

Answer 3

Let's solve both equations step by step:

1. 450 - x = 60 * 7

First, calculate the right side of the equation:

60 * 7 = 420

Now, subtract 420 from both sides of the equation to isolate x:

450 - 420 = x

30 = x

So, x = 30.

2. 480 / x = 100 / 10

To solve for x in this equation, you can cross-multiply:

480 * 10 = 100 * x

4800 = 100x

Now, divide both sides by 100 to isolate x:

x = 4800 / 100

x = 48

So, x = 48.

So, the solutions are:

1. x = 30 for the first equation.
2. x = 48 for the second equation.
