Priscilla has a number riddle for her friends she wants them to guess what number she is thinking of. She tells them that her number can be represented by the x in the equation 3x - 10 = 26 her friends guess 6, 12, 13, 36 using subtraction which guess was the correct number
To find the correct number, we need to solve the equation 3x - 10 = 26 for x.
3x - 10 = 26
Add 10 to both sides:
3x = 36
Divide both sides by 3:
x = 12
Therefore, the correct guess was 12.
