Tina's mom made brownies. When tinas friend came over they ate 1/3 of the brownies. Her sister ate 2 and her dad ate 4. If there are 26 brownies left. How many did her mom make

Let b denote the number of brownies Tina's mom made. We're given:
b - 1/3b - 2 - 4 = 26

Combining like terms, we have:
2b/3 - 6 = 26

Add 6 to each side, we get:
2b/3 = 32

To solve this equation for b, we type it in our math engine and we get:
b = 48
