3x3+(50)X+30= 80, Then What Is X

3x3+(50)X+30= 80, then what is X

 

Answer:

x=\frac{41}{50}

Step-by-step explanation:

Firstly, we will transfer the 80 to the opposite side and chage it to -80, same with the 50x and change also the sign into -50x

Take the whole 50x not just the x only. I tried moving the x only and the answer was not valid.

  • 3 x 3 + 30 -80 = -50x

Simplify the equation.

  • 9 + 30 -80 = -50x
  • 39 -80 = -50x
  • -41 = -50x

Divide both side by -50

  • \frac{-41}{-50} = \frac{-50x}{-50}

Remove the (-) from the number because (-) divided by itself will be (+) and the answer is:

  • x = \frac{41}{50}
