Answer:
z = -1
Step-by-step explanation:
7 - z / -2 - (-1)
7 - z / -2+1
7 - z / -1
-7 +z = -8
z = -1
to check the work
(-1,-1) (-2,7)
7 + 1 / -2 + 1
8 / -1
= -8
Answer:
x = - 5
Step-by-step explanation:
5x + 23 = - 2x - 12 ( add 2x to both sides )
7x + 23 = - 12 ( subtract 23 from both sides )
7x = - 35 ( divide both sides by 7 )
x = - 5
