10n - 13
100
Determine the solution from the set.
x = {8, 9, 10, 11, 12}
-3(x + 4) = -36
x = 8
100
Solve. What inverse operation do you have to use?
4.5x = 9
x = 2
Divide by 4.5 on both sides.

200
Determine the solution from the set.
x = {8, 9, 10, 11, 12}
4(x - 8) = 16
x = 12
200
Solve. What inverse operation do you have to use?
17.55 + x = 81.95
x = 64.40
Subtract by 17.55 on both sides.
200
Determine the pattern in the table, then write an equation for the table.
