Hi Luckschaffer10
simplify 2/7g to 2g/7
subtract 20 from both sides
subtract 3/-4 - 20 to 83/-4
multiply both sides by 7
multiply 83/4 * 7 to 581/4
divide both sides by -2
two negatives make a positive so its now g = 581/4/2
simplify 581/4/2 to 581/4*2
Lastly multiply 4 * 2 to 8
Answer: g = 581/8
*581/8 made into a mixed fraction would be 72 5/8.
