3y - 5 = 16
Check the final answer first, then review the worked steps.
Problem
3y - 5 = 16
Answer
\(y = 7\)
Step-by-step solution
1. Isolate the term with y: To solve the equation $3y - 5 = 16$, we first need to isolate the term containing the variable $y$. We do this by adding $5$ to both sides of the equation:
$$3y - 5 + 5 = 16 + 5$$
$$3y = 21$$
2. Solve for y: Now that we have $3y = 21$, we isolate $y$ by dividing both sides of the equation by $3$:
$$\frac{3y}{3} = \frac{21}{3}$$
$$y = 7$$
