1

Understand the problem

Determine the numerical value of the triangle:

6+△=26 6+{\triangle}=26

2

Step-by-step solution

To solve the equation 6+△=26 6 + \triangle = 26 , we seek the value of △ \triangle . We can easily obtain this by isolating △ \triangle on one side of the equation.

We employ the subtraction method to isolate △ \triangle :

  • Subtract 6 from both sides of the equation:
△=26−6\triangle = 26 - 6

Perform the calculation:

△=20 \triangle = 20

Thus, the numerical value of the triangle is 20 20 .
