Answer:
z = 17
Step-by-step explanation:
To solve this equation, solve for z since x and y are given
First substitute -3 for x and 6 for y in the equation z=-4 x+y+(-1)
z = -4(-3) + 6 - 1
Next multiply -4 and -3 making it 12 + 6 - 1 = z
After that add 6 and 12, which will make it 18 - 1 = z
Lastly subtract 1 from 18. This means z equals 17
