4x-3+5=2x+7-8x      what is the solution for x in the equation?  

 

 

                                                                  4x – 3 + 5  =  2x + 7 – 8x    

This looks pretty straightforward. 

1st, put like terms on the same side.         4x – 2x + 8x  =  7 + 3 – 5   

 

Remember, when you move something    

to the other side of the equals mark,   

you have to change its polarity.  

 

Combine the like terms.                             10x  =  5  

 

Divide both sides by 10.                               x  =  1 / 2    (read as "x equals one-half")    

(five-tenths reduces to one-half)   

 

 

Check answer.                                   (4)(1/2) – 3 + 5  =  (2)(1/2) + 7 – (8)(1/2)  

 

                                                                    2 – 3 + 5  =  1 + 7 – 4   

 

                                                                                4  =  4       

 

NEVER trust an answer that doesn't show the work, like answer #1.   

This site is full of trolls and a** h***s ... that was a rhyme.

Simplify each side: 4x+2=7-6x

Shift 6x: 10x+2=7

Shift 2: 10x=5

Divide by 10: x=1/2.
