Answer: the reason why 3x - 30 = 0 is because x = 10
Step-by-step explanation:
3x - 30 = 0
first we try to get the value of x
so
3x = 30
x = 30/3
x = 10
so the reason why 3x - 30 = 0 is because x = 10
to confirm this
we substitute the value of x=10 into the equation
3x - 30 = 0
3*10 - 30 = 0
30 - 30 = 0
