Final answer:
To solve the equation Y = (2/9)u + 2 for u, subtract 2 from both sides of the equation and multiply both sides by the reciprocal of (2/9), which is 9/2. The equation for u is u = (9/2)(Y - 2).
Step-by-step explanation:
To solve the equation Y = (2/9)u + 2 for u, we need to isolate the variable u on one side. To do this, we'll subtract 2 from both sides of the equation.
Y - 2 = (2/9)u
Next, we'll multiply both sides of the equation by the reciprocal of (2/9), which is 9/2.
(9/2)(Y - 2) = u
Thus, the equation for u is u = (9/2)(Y - 2).
