The soultion of the given equation 1/4x - 3/4 = 7/x for x is 9.
According to the given question.
We have an equation 1/4x - 3/4 = 7/x.
As we know that, as we know that, an equation is a condition on a variable such that two expressions in the variable should have equal value.
Therefore, the solution of the equation 1/4x - 3/4 = 7/x is given by
1/4x - 3/4 = 7/x
⇒ 1/4x - 7/x -3/4 = 0
⇒ 1- 28/4x = 3/4
⇒ 27/4x = 3/4
⇒ 27 = (3/4)(4x)
⇒ 27 = 3x
⇒ 27/3 = x
⇒ x = 9
Hence, the soultion of the given equation 1/4x - 3/4 = 7/x for x is 9.

5/8x + 1/5x can be written with a common denominator:
25/40x+ 8/40x = 99
This can be simplified to:
33/40x = 99
Next times both sides by 40
33x = 3960
Then, divide both sides by 33
x = 3960/33
x = 120
The equivalent ratios are A and D.
Here's an explanation:
When you look at D, you see that 12 is a multiple of 6, and 16 is a multiple of 8. So you know that it looks like they're equivalent. Then you test it out, 12/2=6. 16/2=8. so 12:16 = 6:8. Eyeballing it first can save time sometimes.
