A triangle has one side that measures 12, another side that measures x, and a third side that measures 4 less than x. The perimeter is 26.
Which equation would we use to find the value of x?

To find the value of x, we use the equation:
12 + x + (x - 4) = 26
Simplifying:
2x + 8 = 26
Subtracting 8 from both sides:
2x = 18
Dividing both sides by 2:
x = 9
12 + x + (x - 4) = 26
Simplifying:
2x + 8 = 26
Subtracting 8 from both sides:
2x = 18
Dividing both sides by 2:
x = 9
