Answer 2

Let's break down and solve these equations step by step:

1. (-620 - 14 × 6(-6) + 36) / (-250) = ?

First, simplify the expression within the parentheses: (-620 - 14 × (-36) + 36) / (-250)

Now, perform the multiplications and additions within the parentheses: (-620 + 504 + 36) / (-250)

Combine like terms: (-80) / (-250)

Finally, divide: (-80) / (-250) = 4/5

So, the result of the first expression is 4/5.

2. 720 / (-12 - 36) × (-12) - 4 = ?

First, simplify the expression within the parentheses: 720 / (-48) × (-12) - 4

Now, perform the multiplication: (720 / (-48)) × (-12) - 4

Divide 720 by -48: -15 × (-12) - 4

Now, multiply: 180 - 4

Finally, subtract 4 from 180: 180 - 4 = 176

So, the result of the second expression is 176.

3. 240 - 240 / (-55 + 15) × (-2) = ?

First, simplify the expression within the parentheses: 240 - 240 / (-40) × (-2)

Now, perform the division within the parentheses: 240 - (-6) × (-2)

Multiply -6 by -2: 240 + 12

Finally, add 12 to 240: 240 + 12 = 252

So, the result of the third expression is 252.

Now, let's analyze the equations:

1. х + (-4025) = -3087 Add 4025 to both sides to isolate х: х = -3087 + 4025 х = 938

2. -2573 = -324 This equation is not true, as -2573 is not equal to -324.

3. -2946 - х = 3025 Add х to both sides to isolate х: -2946 - х + х = 3025 + х -2946 = 3025 + х

This equation does not have a unique solution unless you provide more information or constraints on х.

So, the values of х that satisfy the given equations are:

• х = 938 for the first equation.
• No solution for the second equation.
• The third equation does not have a unique solution without additional information.
