Question

If x = 3, y = 4 and z = -2, then 5x - 2y - z =

Answer 1

9

Explanation:

Hey There!

So for this problem all we have to do is plug in the given values into the expression so now we have

5(3) - 2(4) - -2

5x3=15

-2x4=-8

now we have

15-8-(-2)

15-8=7

7-(-2)

remember when you subtract a negative number the two negative signs cancel out and turn into a positive so instead of

7--2 it would be 7+2

7+2=9

so the answer is 9
