Answer 2

Let's break down the equations you provided:

1. В - 70 * 3 = 345 To solve this equation, we need to isolate the variable В. First, let's simplify the multiplication: В - 210 = 345 Next, we can isolate В by adding 210 to both sides of the equation: В = 345 + 210 В = 555

2. а : (400 - 360) = 8 In this equation, we need to calculate the value of the variable а. Let's simplify the division within the parentheses first: а : 40 = 8 To isolate а, we can multiply both sides of the equation by 40: а = 8 * 40 а = 320

3. 45 : 5 * в = 900 Similarly, let's simplify the division first: 9 * в = 900 Now, we can isolate в by dividing both sides of the equation by 9: в = 900 / 9 в = 100

So, the solutions to the given equations are: В = 555 а = 320 в = 100
