The answer to that problem is 149

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.

(5x6)(x)(7x)=(5x6)(x)(85x6)

Simplify

[(5x6)(x)(7)x]=[(5x6)(x)(8)5x6]

7(5x6)=8x

35x42=8x

35x42+42=8x+42

35x8x=8x8x+42

27x=42

27x27=4227

x=4227

Simplify the answer to the lowest term

x=4227÷33

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

x=149
