What is the value of 5y − 6 when y = 4?

Explanation:
Substituting the given value for the variable into the expression and then performing the arithmetic. Replace y with 4: 5y − 6 becomes 5×4 − 6. Compute 5×4 to get 20, then subtract 6 to get 14. So the expression evaluates to 14. The other numbers would arise if the subtraction were forgotten or a different operation were used, but with the correct substitution the result is 14.
