solve: (3/x)/1=(7/x-20)
i keep getting different answers for this question. the last answer i got was 20 (which would make it not a solution) but im not sure if that is right
i wrote it wrong the 1st time. this is the problem.
solve: (3/x)-1=(7/x-20)
(3/x)-1=(7/x-20)
why are there brackets around the right side? Did you mean 7/(x-20) ?
I can only take your question at face value the way you typed it.
Then it would be the same as
3/x - 1 = 7/x - 20
multiply each term by x
3 - x = 7 - 20x
19x = 4
x = 4/19
it suppose to be (3/x)-1=7/(x-20)
To solve the equation (3/x)/1 = (7/(x - 20)), you can follow these steps:
Step 1: Multiply both sides of the equation by x to eliminate the fraction in the left-hand side:
(3/x)/1 * x = (7/(x - 20)) * x
This simplifies to:
3 = 7x/(x - 20)
Step 2: Cross-multiply to get rid of the fraction:
3(x - 20) = 7x
Step 3: Expand and simplify the equation:
3x - 60 = 7x
Step 4: Subtract 3x from both sides:
-60 = 4x
Step 5: Divide both sides by 4 to solve for x:
-60/4 = x
-15 = x
The solution to the equation is x = -15.
If you obtained a different answer, let's go back and check the steps to see if any mistakes were made along the way.
