Which equation, when solved, results in a different value of [tex]$x$[/tex] than the other three?

A. [tex]8.3 = -0.6x + 11.3[/tex]
B. [tex]11.3 = 8.3 + 0.6x[/tex]
C. [tex]11.3 - 0.6x = 8.3[/tex]
D. [tex]8.3 - 0.6x = 11.3[/tex]

Answer :

Let's solve each of the four equations individually to see which one gives a different solution for [tex]\( x \)[/tex].

### Equation 1:

[tex]\[ 8.3 = -0.6x + 11.3 \][/tex]

1. Subtract 11.3 from both sides to isolate the term with [tex]\( x \)[/tex]:
[tex]\[ 8.3 - 11.3 = -0.6x \][/tex]

2. Simplify the left side:
[tex]\[ -3 = -0.6x \][/tex]

3. Divide both sides by [tex]\(-0.6\)[/tex] to solve for [tex]\( x \)[/tex]:
[tex]\[ x = \frac{-3}{-0.6} = 5.0 \][/tex]

### Equation 2:

[tex]\[ 11.3 = 8.3 + 0.6x \][/tex]

1. Subtract 8.3 from both sides to isolate the term with [tex]\( x \)[/tex]:
[tex]\[ 11.3 - 8.3 = 0.6x \][/tex]

2. Simplify the left side:
[tex]\[ 3 = 0.6x \][/tex]

3. Divide both sides by 0.6 to solve for [tex]\( x \)[/tex]:
[tex]\[ x = \frac{3}{0.6} = 5.0 \][/tex]

### Equation 3:

[tex]\[ 11.3 - 0.6x = 8.3 \][/tex]

1. Subtract 11.3 from both sides to isolate the term with [tex]\( x \)[/tex]:
[tex]\[ -0.6x = 8.3 - 11.3 \][/tex]

2. Simplify the right side:
[tex]\[ -0.6x = -3 \][/tex]

3. Divide both sides by [tex]\(-0.6\)[/tex] to solve for [tex]\( x \)[/tex]:
[tex]\[ x = \frac{-3}{-0.6} = 5.0 \][/tex]

### Equation 4:

[tex]\[ 8.3 - 0.6x = 11.3 \][/tex]

1. Subtract 8.3 from both sides to isolate the term with [tex]\( x \)[/tex]:
[tex]\[ -0.6x = 11.3 - 8.3 \][/tex]

2. Simplify the right side:
[tex]\[ -0.6x = 3 \][/tex]

3. Divide both sides by [tex]\(-0.6\)[/tex] to solve for [tex]\( x \)[/tex]:
[tex]\[ x = \frac{3}{-0.6} = -5.0 \][/tex]

### Conclusion

The solutions for the equations are:

- Equation 1: [tex]\( x = 5.0 \)[/tex]
- Equation 2: [tex]\( x = 5.0 \)[/tex]
- Equation 3: [tex]\( x = 5.0 \)[/tex]
- Equation 4: [tex]\( x = -5.0 \)[/tex]

Equation 4 results in a different value for [tex]\( x \)[/tex] compared to the other three equations.
