Question

Solve the equation. $$4+y=12$$

Short answer

The solution to the equation \(4 + y = 12\) is \(y = 8\).

Step-by-step solution

Identify the problem

The problem here is to find the value of \(y\) in the equation \(4+y=12\) which will satisfy the equation.

Isolate the variable

To isolate \(y\) on one side of the equation (that is, to get \(y\) alone on one side), subtract 4 from both sides of the equation.

Execute the operation

Subtracting 4 from both sides of the equation, we get \(y = 12 - 4\).

Simplify the expression

Solving the simple arithmetic on the right-hand side of the equation, we find that \(y = 8\).
