Which is the solution of the equation below, rounded to the nearest tenth? 
 
2.1x – 4.09 = 6.98x + 1.73
 
 A.–0.4
 
 B.–1.1
 
 C.–1.2
 
 D.–0.5

anonymous · Answer

Okay. First look at the constants: -4.09 and 1.73

Subtract 1.73 from both sides to get 

-5.82 + 2.1 x = 6.98x

Are you with me so far?

anonymous · Answer

Now you have to subtract more like terms.

Subtract 2.1 from 6.98 (6.98 - 21) to get

-5.82 = 4.88

@Akpellet_math  Thanks :)

anonymous · Answer

Sorry I mean

-5.82 = 4.88x

anonymous · Answer

Now you have to get the x by itself

This can be done by dividing 4.88 to both sides

-5.82/4.88 = x

Are you allowed to use a calculator for this division? This one is very hard to do mentally.
