Answer :
[tex]2(x+4)=18\ \ \ \ | omiting\ the\ bracket\\\\
2x+8=18\ \ \ | subtract\ 8\\\\
2x=10 \ \ \ \ | divid\ by\ 2
\\\\\x=5[/tex]
2(x+4) = 18
expand the equation 2x + 8 = 18
subtract 8 2x = 10
divide by 2 x = 5
or
2(x+4) = 18
divide by 2 x+4 = 9
subtract 4 x = 5
Remember, whatever you to one side, you do to the other. Your goal is to isolate X!
