add the numbers like x`s to regular so like 28x+22=180 then take the 22 away from the 180 now its 28x=158 then do 158 divded by 28 so x equals 5.64 repeated so then yo know x equals 5.64 so now do 155.6411-65.648+5.643-45.64+3=705943.61664 now that was just my example if the answer equaled 180 so now you know how to solve your problem hope this helps.
