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
