The number above is the tax in addition to the total (By the way I’m leaving it as 1.175 to be accurate and then I can round it in the end when I get my final answer)
4y+5=-31 you subtract 5 from both sides so you get 4y=-36 then you divide by 4 from both sides so you get y=-9 and to check you put -9 in for y and multiply 4 and -9 add 5 to get -31
