Final answer:
To solve the equation 3x - 4 = 11, use algebra tiles to represent the equation and manipulate the tiles to isolate the variable. The value of x is 3.
Step-by-step explanation:
To solve the equation 3x - 4 = 11 using algebra tiles, we can represent 3x by using three positive x tiles. Then we subtract four negative unit tiles from the equation. Next, we move the unit tiles to one side of the equation, and the x tiles to the other side to isolate the variable. Finally, we count the number of x tiles to find the value of x. In this case, there are three x tiles, so x = 3.
