The answer to that problem is 14/9149

Explanation:

In the equation, you need to remove the denominator in both sides of the given equation. To do that, you need to multiply both sides by their corresponding denominator.

(5x-6)(x)(7/x)=(5x-6)(x)(8/(5x-6))(5x6)(x)(7x)=(5x6)(x)(85x6)

Simplify

[[(5x-6)(x)(7)]/x]=[[(5x-6)(x)(8)]/(5x-6)][(5x6)(x)(7)x]=[(5x6)(x)(8)5x6]

7(5x-6)=8x7(5x6)=8x

35x-42=8x35x42=8x

35x-42+42=8x+4235x42+42=8x+42

35x-8x=8x-8x+4235x8x=8x8x+42

27x=4227x=42

(27x)/27=42/2727x27=4227

x=42/27x=4227

Simplify the answer to the lowest term

x=42/27-:3/3 x=4227÷33

Since both of them has the factor of 3, we will divide both the numerator and the denominator by 3.

x=14/9x=149
