Answer 2

To solve the equations and simplify the expressions, follow these steps:

1. Solve the equation: -2x + 5 = 2 Subtract 5 from both sides to isolate -2x: -2x = 2 - 5 -2x = -3 Divide both sides by -2 to solve for x: x = -3 / -2 x = 3/2 So, the answer is 1) 3/2.

2. Simplify the equation: -4x + 3.6 = 3x - 2.1 Move all terms with x to the left side and constants to the right side: -4x - 3x = -3.6 - 2.1 -7x = -5.7 Divide both sides by -7 to solve for x: x = -5.7 / -7 x = 5.7 / 7 So, the answer is 2) -4x + 3x = -3.6 - 2.1.

3. Simplify the equation: 6x - 1.3 = -2x + 2.2 Move all terms with x to the left side and constants to the right side: 6x + 2x = 2.2 - 1.3 8x = 0.9 Divide both sides by 8 to solve for x: x = 0.9 / 8 So, the answer is 2) 6x - 2x = 2.2 - 1.3.
