Question 335017
if i am teatching a class how would i teach them how to solve 
3-5(x+2)=3(x+1)+6

-------------------
Your Problem:
3-5(x+2)=3(x+1)+6
Explain the distributive law
and apply it to the parentheses
on the left and on the right side 
to get:
3-5x-10 = 3x+3+6
-----
Simplify each side by combining "like" terms.
-5x-7 = 3x+9
-----
Add 5x to both sides to get:
-7 = 8x+9
Subtract 9 from both sides to get:
8x = -16
Divide both sides by 8 to get:
x = -2
-----------------------------------------------
Teach the students how to check their answers so
they will know if their answers are correct.
3-5(x+2)=3(x+1)+6
Substitute -2 for "x":
3-(-2+2) = 3(-2+1)+6
3-0 = 3(-1)+6
3 = -3+6
3 = 3
=====================
Tell the students this means they have found 
a numerical value that makes the original 
equal true when it is substituted for the 
letter "x".
