Question

2x(x+4)+7+=(x+8)+ 2x(x+1)+12=

Answer 1

Answer:

x=2.600

Step-by-step explanation:

2x(x+4)+7+=(x+8)+ 2x(x+1)+12

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

  ->        2*x*(x+4)+7+-((x+8)+2*x*(x+1)+12)=0

-> ((2x•(x+4))+7)-(((x+8)+2x•(x+1))+12)  = 0

->  (2x • (x + 4) +  7) -  (2x2 + 3x + 20)  = 0

->  5x - 13  = 0

-> Add  13  to both sides of the equation :  

                     5x = 13

Divide both sides of the equation by 5:

                    x = 13/5 = 2.600
