You can put this solution on YOUR website! 2/5x=-10
First, you need to isolate the "x". Since the "x" term is in the denominator of a fraction, multiply both sides of the equation by the inverse of 1/5x which would be 5x/1 (just flip it):
2/5x (5x/1) = -10 (5x/1)
Cancel and Simplify you get:
2 = -10 (5x)
Continue to simplify:
2 = -50x
Divide both sides by -50 to further isolate the "x":
2/-50 = x
Reduce:
1/-25 = x or -1/25 = x
Be sure to check the answer by plugging the value of x (which we think is -25) back into the original problem:
2/5x=-10
2/(5 (-1/25)) = -10
Enter the left side of the equation into your calculator:
2 divided by 5/(-1/25) = -10
Entire this equation into your calculator and you should get:
-10 = -10
