Answer 2

It seems like you've provided an equation and an expression. Let's break down each part:

Equation: 4.8 + 5x + (-1.8) = -2 Expression: 24 - 3 - 42 * 0.5 - 2 * 0.51 - 12

I'll solve these step by step:

1. Equation: 4.8 + 5x + (-1.8) = -2

First, let's simplify the left-hand side: 4.8 - 1.8 = 3

So the equation becomes: 3 + 5x = -2

Subtracting 3 from both sides: 5x = -5

Dividing by 5: x = -1

2. Expression: 24 - 3 - 42 * 0.5 - 2 * 0.51 - 12

Performing calculations step by step: 24 - 3 = 21 42 * 0.5 = 21 2 * 0.51 = 1.02

Now, the expression becomes: 21 - 21 - 1.02 - 12

Subtracting 21 from 21: 0 - 1.02 - 12

Subtracting 1.02 from 0: -1.02 - 12

Adding -1.02 and -12: -13.02

So, the value of the expression is -13.02.

In summary:

• The solution for the equation 4.8 + 5x + (-1.8) = -2 is x = -1.
• The value of the expression 24 - 3 - 42 * 0.5 - 2 * 0.51 - 12 is approximately -13.02.
