Which of these equations, when solved, gives a different value of x than the other three?
9.1 = -0.2x + 10
10 = 9.1 + 0.2x
10 – 0.2x = 9.1
9.1 – 10 = 0.2x

Respuesta :

Answer:

D. 9.1 – 10 = 0.2x

Step-by-step explanation:

I got it right

The odd equation with a different value is equation d

Data;

  • 9.1 = -0.2x + 10
  • 10 = 9.1 + 0.2x
  • 10 - 0.2x = 9.1
  • 9.1 - 10 = 0.2x

Linear Equation

To solve this problem, we have to solve each of the linear equations and get the value of x.

a)

[tex]9.1 = -0.2x + 10\\10 - 9.1 = 0.2x\\0.9 = 0.2x\\\frac{0.2x}{0.2} = \frac{0.9}{0.2} \\x = 4.5[/tex]

b)

[tex]10 = 9.1 + 0.2x\\0.2x = 10 - 9.1\\0.2x = 0.9\\\frac{0.2x}{0.2} = \frac{0.9}{0.2} \\x = 4.5\\[/tex]

c)

[tex]10 - 0.2x = 9.1\\-0.2x = 9.1 - 10\\-0.2x = -0.9\\x = 4.5[/tex]

d)

[tex]9.1 - 10 = 0.2x\\0.2x = -0.9\\x = -4.5[/tex]

The odd equation with a different value is equation d
