Answer:
Step-by-step explanation:
solution z = -7
-3=z+4
-3 -4 = Z + 4 -4
-3 -4 = z + 4 - 4
-7 = z + 4 - 4
-7 = z + 4-4
-7 = z
-7 = z
z=-7
solution z = -7
Hello!
Let's solve this equation for z.
In order to do that, simply add 3 to both sides:
0=z+7
Move z to the left:
-z=7
Divide both sides by -1 in order to remove the minus next to z:
z=-7 (answer)
Hope everything is clear.
