Evaluate the expression for the for the given value of the variable.....................

4(x-4; x = 7

Can someone help please, I have been having trouble with this problem for sometime now.

substitute 7 in x spot

so 4 (7-4)=4(3)=12

Sure! To evaluate the expression 4(x - 4) for the given value of the variable x = 7, you need to substitute the value of x into the expression and perform the calculations.

Let's begin by substituting x = 7 into the expression:

4(7 - 4)

Next, simplify the expression inside the parentheses:

4(3)

Now, multiply the 4 outside the parentheses by 3:

4 * 3 = 12

Therefore, the value of the expression 4(x - 4) when x = 7 is 12.
