Answer:
answer is x=5, not x=6
Step-by-step explanation:
I don't really understand how this is structured, but the correct way of solving this is
2(3x − 4) = 8 + 2x + 4
do distributive property.
6x - 8 = 8 + 2x + 4
subtract 2x on both sides.
you get...
4x - 8 = 12
add 8 on both sides.
4x =20
divide by 4
x = 5
-1-6x=x-15
-6x+x=-15 +1
-6x^2=-14
x^2=-14 +6
x^2= -8
x=_/8
x=4
Factor by grouping
( 2 x + 5 ) ( x + 4 )
