EVALUATE 5x - 2y + 4z WHEN x=3, y=2, AND z=4 ??

I showed you how to do the last problem like this. Now it's your turn.

I'll be glad to check your answer.

I BELIEVE THE CORRECT ANSWER IS 27

You're right! :-)

To evaluate the expression 5x - 2y + 4z when x = 3, y = 2, and z = 4, you need to substitute these values into the expression and perform the calculations.

Step 1: Replace x, y, and z in the expression.
5x - 2y + 4z = 5(3) - 2(2) + 4(4)

Step 2: Perform the calculations within the parentheses first.
5(3) = 15
2(2) = 4
4(4) = 16

Step 3: Substitute the calculated values back into the expression.
5x - 2y + 4z = 15 - 4 + 16

Step 4: Continue performing the calculations from left to right, following the order of operations.
15 - 4 = 11
11 + 16 = 27

Therefore, when x = 3, y = 2, and z = 4, the value of the expression 5x - 2y + 4z is 27.
