Question

PLEASE HELP!!!!!
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

Answer 1

Answer: 9.1-10=0.2x

Step-by-step explanation:

9.1 = −0.2x + 10

−0.2x + 10 = 9.1

−0.2x + 10 − 10 = 9.1 −10

−0.2x = −0.9

−0.2x / −0.2 = −0.9 / −0.2

x=4.5

10 = 9.1 + 0.2x

10 = 0.2x + 9.1

0.2x + 9.1 = 10

0.2x + 9.1 − 9.1 = 10 − 9.1

0.2x = 0.9

0.2x / 0.2 = 0.9 / 0.2

x=4.5

10 − 0.2x = 9.1

10 + (−0.2x) = 9.1

−0.2x + 10 = 9.1

−0.2x + 10 − 10 = 9.1 − 10

−0.2x = −0.9

−0.2x / −0.2 = −0.9 / −0.2

x=4.5

9.1 - 10 = 0.2x

-0.9 = 0.2x

-0.9 / 0.2 = 0.2x / 0.2

x= -4.5
