Answer:
- 2/5x=7/20x+1/4
- -3/4=-1/20x-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.
7<n<8 is the right answer
<span>5x+10 = y
Subtract 10 from both sides.
5x = y - 10
Divide both sides by 5.
x = 1/5y - 2
Plugin 1/5y - 2 for the y.
5(1/5y - 2)
1 - 10 + 10 = y
1 = y
