The solution to the given equation is y = 3
Solving linear equations
From the given question, we are to complete the process of solving the equation.
<h3>What is the linear equation?</h3>
A linear equation is a pattern of numbers with proportional increase or decrease that is used to represent a line graph.
The given equation is
3(y + 1) = 12
Now, dividing both sides of the equation by 3, we get

y + 1 = 4
Then, subtract 1 from both sides,
That is, y + 1 - 1 = 4 - 1
y = 3
Hence, the solution to the given equation is y = 3
