2x-21=3y divide by 3. 2/3x-7=y. So at 7 it crosses
5x - 3y - z
By hypothesis, x = -2, y = 2 and z = -3.
So you all need to do is replace each letter by its value and do the calculus:
5x - 3y - z = 5*(-2) - 3(2) - (-3)
= -10 - 6 + 3=
=-16 + 3
= -13
So when x = -2, y = 2 and z = -3
5x - 3y - z = -13 (answer d)
Hope this helps! :)
The answer to that would be 3/8
Don’t mind my math homework- But ya the answer would be -1/3. You’re welcome I got your back :)
