Solve the Equation: Finding the Value in 8 + Triangle = 30

To solve this problem, we'll follow these steps:

• Step 1: Set up the equation.
• Step 2: Isolate the triangle symbol using subtraction.
• Step 3: Calculate the numerical value of the triangle.

Now, let's work through each step:

Step 1: Set up the equation:

We start with the equation $8 + \triangle = 30$.

Step 2: Isolate the triangle symbol:

To find $\triangle$, we subtract $8$ from both sides of the equation:

$\triangle = 30 - 8$

Step 3: Calculate the numerical value of the triangle:

Performing the subtraction gives us:

$\triangle = 22$

Therefore, the solution to the problem is $\triangle = 22$.
