Answer 2

Let's solve each equation step by step:

1. 1.5 - (3 + x) = 2 First, simplify the expression inside the parentheses: 1.5 - 3 - x = 2 Next, combine like terms on the left side: -1.5 - x = 2 To isolate the variable, we'll add 1.5 to both sides: -1.5 - x + 1.5 = 2 + 1.5 Simplifying further:

• x = 3.5 Finally, multiply both sides by -1 to solve for x: x = -3.5

2. -x + (x + 2.7) = 3 Let's simplify the expression inside the parentheses: -x + x + 2.7 = 3 The x terms cancel each other out, leaving us with: 2.7 = 3 However, this equation is not true. There is no value of x that satisfies it. So, there is no solution to this equation.

3. -2 + (3.1 - x) = 3 Again, simplify the expression inside the parentheses: -2 + 3.1 - x = 3 Combine like terms on the left side: 1.1 - x = 3 To isolate the variable, we'll subtract 1.1 from both sides: 1.1 - x - 1.1 = 3 - 1.1 Simplifying further:

• x = 1.9 Multiply both sides by -1 to solve for x: x = -1.9

In summary: For the given equations:

1. x = -3.5
2. No solution
3. x = -1.9
