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

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

Answer :

To find the equation that results in a different value of [tex]\( x \)[/tex] from the others, let's consider each equation and solve them step by step.

1. Equation 1:
[tex]\[
8.3 = -0.6x + 11.3
\][/tex]
To solve for [tex]\( x \)[/tex], first isolate [tex]\( x \)[/tex] by subtracting 11.3 from both sides:
[tex]\[
8.3 - 11.3 = -0.6x
\][/tex]
Simplify:
[tex]\[
-3 = -0.6x
\][/tex]
Divide both sides by [tex]\(-0.6\)[/tex]:
[tex]\[
x = 5
\][/tex]

2. Equation 2:
[tex]\[
11.3 = 8.3 + 0.6x
\][/tex]
Isolate [tex]\( x \)[/tex] by subtracting 8.3 from both sides:
[tex]\[
11.3 - 8.3 = 0.6x
\][/tex]
Simplify:
[tex]\[
3 = 0.6x
\][/tex]
Divide both sides by [tex]\(0.6\)[/tex]:
[tex]\[
x = 5
\][/tex]

3. Equation 3:
[tex]\[
11.3 - 0.6x = 8.3
\][/tex]
Isolate [tex]\( x \)[/tex] by subtracting 11.3 from both sides:
[tex]\[
-0.6x = 8.3 - 11.3
\][/tex]
Simplify:
[tex]\[
-0.6x = -3
\][/tex]
Divide both sides by [tex]\(-0.6\)[/tex]:
[tex]\[
x = 5
\][/tex]

4. Equation 4:
[tex]\[
8.3 - 0.6x = 11.3
\][/tex]
Isolate [tex]\( x \)[/tex] by subtracting 8.3 from both sides:
[tex]\[
-0.6x = 11.3 - 8.3
\][/tex]
Simplify:
[tex]\[
-0.6x = 3
\][/tex]
Divide both sides by [tex]\(-0.6\)[/tex]:
[tex]\[
x = -5
\][/tex]

From these calculations, we find that equations 1, 2, and 3 all result in [tex]\( x = 5 \)[/tex], while equation 4 results in [tex]\( x = -5 \)[/tex]. Therefore, equation 4 is the one that results in a different value of [tex]\( x \)[/tex] than the other three equations.
