Evaluate the expression 4x − 3y when x = 6 and y = 2.

Explanation:
Substitute the given values into the expression and follow the order of operations. Compute 4x as 4×6 = 24 and 3y as 3×2 = 6. Then subtract the second product from the first: 24 − 6 = 18. So the expression evaluates to 18. The key idea is to replace the variables with numbers and perform the multiplications before the subtraction.
