Question

Solve for x 5 (x+2)=8x+20

Answer 1

First, Distributive Property

5 (x+2)=8x+20
5x+10=8x+20           *Move constants and variables to opposite sides*
-5x       -5x
-----------------
10=3x+20
-20     -20
-------------
-10=3x
----- -----
3      3

x= -10/3

Answer 2

Distribute the 5 outside the parentheses into the parentheses.
5(x+2)=8x+20
5x+10=8x+20
Bring x to one side, other numbers to another
5x+10=8x+20
-8x       -8x
     -10      -10
-3x=10
divide by -3
x=-10/3
approximately -3.33333333
