Answer:
i believe its the second part thats wrong  
Step-by-step explanation:
1 Distribute
−5(−2+10)=20
10−50=20
2 Add 50 to both sides of the equation
10−50=20
10−50+50=20+50
3 Simplify
Add the numbers
10x−50+50=20+50 
10=20+50
Add the numbers 
10x =20 + 50
10x=10
4 Divide both sides of the equation by the same term
10x = 70
10x   70
---- = ----
10      10
5 Simplify
Cancel terms that are in both the numerator and denominator
10x   70
---- = ----
10      10
       70
x  = ----
        10 
     
         70
x  = ----
        10  
x=7 
Solution
 = 7
