To evaluate an expression, you simply substitute the given values of the variables into the expression and perform the necessary calculations.

1) Evaluate a - 13 when a = 33:
Substitute the value of a into the expression:
a - 13 = 33 - 13
Now, perform the calculation:
33 - 13 = 20

Therefore, when a = 33, a - 13 equals 20.

2) Evaluate 3x + 2y - 2z when x = 5, y = 2, and z = 1:
Substitute the values of x, y, and z into the expression:
3x + 2y - 2z = 3(5) + 2(2) - 2(1)
Now, perform the calculation:
3(5) + 2(2) - 2(1) = 15 + 4 - 2
Combine like terms:
15 + 4 - 2 = 19 - 2
Perform the final calculation:
19 - 2 = 17

Therefore, when x = 5, y = 2, and z = 1, 3x + 2y - 2z equals 17.

3) Evaluate 6a + 4b - 3c when a = 4, b = 7, and c = -2:
Substitute the values of a, b, and c into the expression:
6a + 4b - 3c = 6(4) + 4(7) - 3(-2)
Now, perform the calculation:
6(4) + 4(7) - 3(-2) = 24 + 28 + 6
Combine like terms:
24 + 28 + 6 = 52 + 6
Perform the final calculation:
52 + 6 = 58

Therefore, when a = 4, b = 7, and c = -2, 6a + 4b - 3c equals 58.
