Question

3x-30=0
why does it equal 0 and how would I solve for it

Answer 1

Answer: the reason why 3x - 30 = 0 is because x = 10

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
