-3/5x - 7/20x + 1/4x= -56
romanna [79]

Answer:

x = 80

Step-by-step explanation:

Combine − 3/5x and 7/20x to get -19/20x.

Then combine -19/20x and 1/4x and you get -7/10x.

Then you multiply both sides by -10/7 which is the reciprocal of -7/10.

Make -56(-10) one fraction.

Multiply -56 and -10 and you get 560.

Then divide 560 by 7 to get 80.

By taking x as subject the formula becomes x = (v² - u²)/2a.

<h3>What is Equation?</h3>

An equation is a mathematical statement with an 'equal to=' symbol between two expressions that have equal values.

Here given equation:

     2ax = v² - u²

      x = (v² - u²)/2a

Thus, by taking x as subject the formula becomes x = (v² - u²)/2a.
