To solve the problem we must know about Expression.
What is Expression?
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
The equation that when solved for x gives a different value of x is equation 2.
Given to us
- 9.1 = -0.2x+10
- 10 = 9.10+2x
- 10 – 0.2x = 9.1
- 9.1 – 10 = -0.2x.
1. 9.1 = -0.2x+10
[tex]9.1 = -0.2x+10 \\\\9.1-10=-0.2x\\\\-0.9=-0.2x\\\\x= \dfrac{-0.9}{-0.2}\\\\x = 4.5[/tex]
Thus, the value of x is 4.5
2. 10 = 9.10+2x
[tex]10 = 9.10+2x\\\\10-9.10=2x\\\\0.9=2x\\\\x=\dfrac{0.9}{2}\\\\x = 0.45[/tex]
Thus, the value of x is 0.45
3. 10 – 0.2x = 9.1
[tex]10 - 0.2x = 9.1\\\\-0.2x = 9.1-10\\\\-0.2x=-0.9\\\\x = \dfrac{-0.9}{-0.2}\\\\x=4.5[/tex]
Thus, the value of x is 4.5
4. 9.1 – 10 = -0.2x
[tex]9.1 - 10 = -0.2x\\\\-0.9 = -0.2x\\\\x=\dfrac{-0.9}{-0.2}\\\\x=4.5[/tex]
Thus, the value of x is 4.5
Hence, the equation which when solved for x gives a different value of x is equation 2.
