6(4x + 5) = 3(x + 8) + 3
24x + 30 = 3x + 24 + 3
24x + 30 = 3x + 27
24x - 3x = 27 - 30
21x = - 3
x = -3/21
x = - 0.143 <==

Hey there! :D

6(4x+5)=3(x+8)+3

Distribute. 

24x+30=3x+24+3

24x+30=3x+27

Subtract 30 on both sides. 

24x= 3x-3

Subtract 3x on both sides. 

21x=3

Divide both sides by 21. 

x=0.142857... the question said hundredth so:

x=0.143

I hope this helps!
