9 divided by the sum of x and 4 is equal to 6 divided by x minus 4.
Build our two algebraic expressions first:
9 divided by the sum of x and 4
9/(x + 4)
6 divided by x minus 4
6/(x - 4)
The phrase is equal to means and equation, so we set the algebraic expressions equal to each other:
9/(x + 4) = 6/(x - 4) <-- This is our algebraic expression
If the problem asks you to solve for x, we cross multiply:
9(x - 4) = 6(x + 4)
To solve for x, we type this equation into our search engine and we get:
x = 20
