Answer 2

To solve the equation 7 - (3 + 4x) = -2, we'll follow these steps:

1. Simplify the expression inside the parentheses: 7 - (3 + 4x) = 7 - 3 - 4x = 4 - 4x

2. Rewrite the equation using the simplified expression: 4 - 4x = -2

3. Move the constant term to the other side of the equation by adding 4 to both sides: 4 - 4x + 4 = -2 + 4 4 - 4x + 4 = 2

   Simplifying further: 8 - 4x = 2

4. Move the variable term to the other side of the equation by subtracting 8 from both sides: 8 - 4x - 8 = 2 - 8 -4x = -6

5. Divide both sides by -4 to solve for x: (-4x) / (-4) = (-6) / (-4) x = 3/2

Therefore, the solution to the equation 7 - (3 + 4x) = -2 is x = 3/2, which is option в) 1.5.
