Evaluate 12.7 - x for x= 8.41
agasfer [191]

Answer:

x=  

10

429

​  

 

​  

≈2.071231518

x=−  

10

429

​  

 

​  

≈−2.071231518

Step-by-step explanation:

12.7−xx=8.41

Multiply x and x to get x  

2

.

12.7−x  

2

=8.41

Subtract 12.7 from both sides.

−x  

2

=8.41−12.7

Subtract 12.7 from 8.41 to get −4.29.

−x  

2

=−4.29

Divide both sides by −1.

x  

2

=  

−1

−4.29

​  

 

Expand  

−1

−4.29

​  

≈4.29 by multiplying both numerator and the denominator by 100.

x  

2

=  

−100

−429

​  

 

Fraction  

−100

−429

​  

≈4.29 can be simplified to  

100

429

​  

=4.29 by removing the negative sign from both the numerator and the denominator.

x  

2

=  

100

429

​  

 

Take the square root of both sides of the equation.

x=  

10

429

​  

 

​  

 

x=−  

10
