5/8 = x+7/ 2 We need to start by doing cross multiply (8)(2) = (x+7)*5 16 = 5x + 35 5x = 35 - 16 5x =-19 x = -19/5
The correct answer is -19/5
-------------------------------------------------------------------------- The mistake is easy to see. Instead of doing 35 - 16 { they did 35+16 which is wrong because you are transferring 16 to the opposite so you must change the positive sign as well.}
I hope that helps, please let me know if you have further questions about my answer.
