Answer: 12
Step-by-step explanation: Here, we have the expression 4x - 8 and we want to evaluate the expression when x is equal to 5.
To evaluate an expression, we simply plug the value of the variable into the expression and solve.
So here, since x is equal to 5, we have 4(5) - 8.
4 x 5 is equal to 20 so we have 20 - 8 which is equal to 12.
So the value of our expression when x is equal to 5 is 12.
