You can put this solution on YOUR website! 6u+5(u+3)= 4 solve for u To solve for a variable means to isolate the variable.
 We want to remove the parentheses first.  To do this, we use the distributive rule.  Whenever you see a parentheses, remove it as your first step.
 6u+5(u+3)= 4
 6u + 5u + 15 = 4
 11u + 15 = 4
 11u = 4 - 15
 11u = -11
 u = -11/11
 u = -1
