Question

When solving the equation 2/3 b 5 = 7, you should first ? from both sides. Then you should multiply both sides by the ? of ?. Your answer will be ? .

Answer 1

Depends on the question...

If your question is 2/3b + 5 = 7, then follow this one

`(2)/(3)b + 5 = 7\\\\\sf You~ first~subtract~ 5 ~on ~both~ sides\\\\Then ~you~multiply~by~(3)/(2)~on~both~sides.\\\\ So...\\\\ (2)/(3)b + 5 - 5 = 7 - 5\\\\(2)/(3)b = 2\\\\(2)/(3)b * (3)/(2) = 2 * (3)/(2)\\\\b = 3`
Your final answer will be b = 3


If your question is 2/3b - 5 = 7, then follow this one

`(2)/(3)b - 5 = 7\\\\\sf You~ first~add~ 5 ~on ~both~ sides\\\\Then ~you~multiply~by~(3)/(2)~on~both~sides.\\\\ So...\\\\ (2)/(3)b - 5 + 5 = 7+5 \\\\(2)/(3)b = 12\\\\(2)/(3)b * (3)/(2) = 12 * (3)/(2)\\\\b =18`
Your final answer will be b = 18
