4. $x + 2 = 4$
2.
Which equation does the set of tiles represent?

$=$
1. $x + 3 = 8$
2. $x - 3 = 8$
3. $x + 8 = 11$
4. $x - 8 = 11$
3.
Which equation does the set of tiles represent?

$=$
1. $2x + 1 = 5$
2. $2x - 1 = 5$
3. $x + 2 = 5$
4. $x - 2 = 5$
4.
Which equation does the set of tiles represent?

$=$
1. $2x - 4 = 10$
2. $2x + 4 = 10$
3. $2x - 4 = -10$
