Question

15. What value of x makes this equation true?​

Answer 1

C: 33

Explanation:

`(x)/(3)  -7 = (x)/(11) +1\\\\((11)/(11) * (x)/(3) ) -7 = ((3)/(3) * (x)/(11)) +1\\`

`(11x)/(33) -7 = (3x)/(33) +1`

`(11x)/(33)  - (3x)/(33) = 1 + 8`

`(8x)/(33)  = (8*33)/(33) \\(8x)/(33) = (264)/(33) / :33\\8x= 264\\x = 264/8\\\\x= 33`

Answer 2

33

Explanation:

I used Trial and Error and 33 is the only whole number that went in to replace x.
