Evaluate the following expression using the values given find 5x - 3y - Z if x equals -2 y equals 2 + z equals -3

If you had 5x - 3y - z you would have to substitute the values into the equation. So, you would have 5(-2) - 3(2) - (-3). This means you would have -10-6+3. Now, you would just add them all together. -10-6 is -16 and -16 + 3 is -13. This will be give you your answer of -13.

your answer is 23/2 - 13.5

step-by-step explanation:

7/2 evaluates to

multiply x and 4.5

multiply x and 1

the x just gets copied along.

the answer is x

x

4.5*x evaluates to 4.5x

multiply 3 and 4.5x

multiply 1 and x

the x just gets copied along.

x

4.5*x*3 evaluates to 13.5x

7/2-4.5*x*3 evaluates to

  + 8 =

the answer is

7/2-4.5*x*3+8 evaluates to

the answer is 37
