Eight subtracted from four times a number is -120?

-28 because if you add 8 to -120 you get -112 then divide it by 4 and you got -28

Add back the 8 to see what it was before the problem is solved. -120+8=112 the divide by 4 cause it’s the opposite of multiplying. -112/4=-28 and you can go back and check it by doing -28*4=-112-8=-120

Sin(a)+cos(a)+cot(a)-1=2(csc(x)+1)
