To solve for x, we'd have to know what this expression equals.
9 - - 6 + 20 = 35
y=16 x= -4
-7m + 20 = -17m - 1010m = -30m = -3
-28
Better formatting is cos(2x+20)=-0.5
Negative 15 plus positive 20 equals 20 minus 15, which equals 5.
y equals negative 8.
(20 - x)/5
20
To solve for x, we'd have to know what this expression equals.
x = -20
9 - - 6 + 20 = 35
y=16 x= -4
-7m + 20 = -17m - 1010m = -30m = -3

Your question is not very clear. Are you asking: solve for x where negative 4 over x equals negative 20. x equals 1/5 (one fifth)
