Solve the equation: -2x+3=5 show your work.

-2x+3=5
Subtract 3 from both sides
-2x=2
Divide both sides by -2 so that the only thing remaining on one side is the variable x
Final x= -1

-2x+3=5
      -3   -3

cancel 0ut 3s

5-3=2

-2x=2           this is suppose to look like a fraction
= ---
-2       -2

x=-1

Hello! i hope this
since the cosine is the ratio of the adjacent side to the hypotenuse, you can see that cos 60° = ½. answer. according to the property of cofunctions (topic 3), sin 30° is equal to cos 60°. sin 30° = ½.
