Horatio is solving the equation -3/4+2/5x=7/20x-1/2. which equations represent possible ways to begin solving for x? check all that apply. 2/5x=7/20x+1/4 2/5x=7/20x+5/4 -3/4=-1/20x-1/2 -3/4=3/4x-1/2 -3/4+1/20x=-1/2

Step-by-step explanation:

If you add 3/4 to both sides of the equation, you get ...

... 2/5x = 7/20x + 1/4 . . . . first choice

If you subtract 2/5x from both sides of the equation, you get ...

... -3/4 = -1/20x -1/2 . . . . third choice

If you subtract 7/20x from both sides of the equation, you get ...

... -3/4 +1/20x = -1/2 . . . . last choice

Choices 2 and 4 are erroneous versions of choices 1 and 3, so do not apply.
