Solve for x: 3 over 4 x + 5 over 8 = 4x

x = write your answer as a fraction in simplest form. use the "/" symbol for the fraction bar.

The given equation is:3/4x+5/8=4x

We are then asked to find x. 
First step: (5/8) = 4x -(3/4)x
subtract (3/4)x on both sides. 

Then divide 3.25 to both sides of the equation:  5/8 = 3.25x

x = 5/26

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
