Answer 2

1) 0.09 - x = -1 First, we need to isolate the variable x by adding x to both sides of the equation: 0.09 - x + x = -1 + x 0.09 = -1 + x Then, we need to isolate x by adding 1 to both sides of the equation: 0.09 + 1 = -1 + 1 + x 1.09 = x So, the solution is x = 1.09

2) 1/6 - x = -1/12 First, we need to isolate the variable x by subtracting 1/6 from both sides of the equation: 1/6 - x - 1/6 = -1/12 - 1/6 -x = -1/12 - 2/12 -x = -3/12 Then, we need to isolate x by multiplying both sides of the equation by -1: x = 3/12 x = 1/4 So, the solution is x = 1/4

3) 1 + 1/4 - x = 0.25 First, we need to simplify the left side of the equation: 1 + 1/4 - x = 5/4 - x Then, we need to isolate the variable x by subtracting 5/4 from both sides of the equation: 5/4 - x - 5/4 = 0.25 - 5/4 -x = -1/4 Finally, we need to isolate x by multiplying both sides of the equation by -1: x = 1/4 So, the solution is x = 1/4

The solutions to the given equations are: 1) x = 1.09 2) x = 1/4 3) x = 1/4
