I was presented with 4 equations as possible solutions for x=4. The one below was the correct one but I converted 14/3 to the proper fraction 4-2/3. Then I added 2/3 + 4 = 4-2/3. I found the right equation that way but did I solve it the right way? Would this be acceptable on a test.

x=4

2/3 + x = 14/3
