Answer:

i believe its the second part thats wrong

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
