Please answer these questions with steps explaining how to solve them. Also please go step by step explaining what you did. x/3 - 3 = x/9 + 3

what does x mean, like what number does it represent in this situation

x = 27

Step-by-step explanation:

I made '3' into 9/3

x/3 - 9/3 = x/9 + 9/3

convert terms to fractions with a denominator of 9

x/3 = 3x/9

9/3 = 27/9

3x/9 - 27/9 = x/9 + 27/9

(3x-27)/9 = (x+27)/9

since each denominator equals 9 we can set the numerators equal to each other:

3x - 27 = x + 27

3x = x + 54

2x = 54

x = 27

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315
