Hi Dear Kitkat ;
• 3x + 4 = 16
• 3x + 4 - 16 = 0
• 3x + ( 4 - 16 ) = 0
• 3x - 12 = 0
• 3x = 12
• x = 12 / 3
• x = 4
Good Luck Darling♣

3x + 4 = 16
-> 3x = 16 - 4
-> 3x = 12
-> x = 4
Check:
3x + 4 = 16
-> 3(4) + 4 = 16
-> 12 + 4 = 16
-> 16 = 16
...Cool! Using Yahoo to get the answer huh? Why haven't I thought of that when I was yet a sucker at this subject? :)

3x + 4 = 16 (subtract four from both sides)
3x = 12 (divide both sides by three)
x= 4
