Which of these equations, when solved, gives a different value of x than the other three? 1. 9.1 = -0.2x + 10 2. 10 = 9.1 + 0.2x 3. 10 – 0.2x = 9.1 4. 9.1 – 10 = 0.2x

4. 9.1 – 10 = 0.2x

X= -4.5

Step-by-step explanation:

Let's solve for x in the equations given below

1. 9.1 = -0.2x + 10

9.1 - 10 = -0.2x

-0.9= -0.2x

-0.9/-0.2= x

4.5 = x

2. 10 = 9.1 + 0.2x

10-9.1 = 0.2x

0.9= 0.2x

0.9/0.2 = x

4.5 = x

3. 10 – 0.2x = 9.1

10-9.1= 0.2x

0.9= 0.2x

0.9/0.2= x

4.5 = x

4. 9.1 – 10 = 0.2x

-0.9 = 0.2x

-0.9/0.2= x

-4.5 = x

The different equation is equation 4

Reason because it's answer gave a negative value of x while others gave a positive value of x.

But in magnitude they all have same value of x
