Question 66479
(1)  2x+9x-24/10+10x+6/6=26

First, note that 6/6=1 
And  2x+9x+10x=21x
Also  24/10=12/5
Now lets rewrite the equation:

(2)  21x-12/5+1=26  Multiply every term by 5 to get rid of the fraction

5(21x)-12(5/5)+1(5)=26(5) simplifying:

105x-12+5=130 add 7 to both sides:

105x-7+7=130+7
105x=137  
x=137/105


ck
substitute in (2)

21x-12/5+1=26  
21(137/105)-(12/5)+1=26
137/5-12/5+5/5=26
130/5=26
26=26
