Answer: z=24
Explanation:
switch sides
10+z/-3=2
subtract by 10 both sides of an equation
10+z/-3-10=2-10
simplify
z/-3=-8
multiply -3 both sides of an equation
z(-3)/-3=(-8)(-3)
simplify
parenthesis must be multiply
-8*-3=-24
its going to be change negative to positive.
8*3=24
24/3=8
24/8=3
3*8=24
z=24
Hope this helps!
Thanks!
Have a great day!
