Respuesta :

X = 4/15 or 0.26

First add the numbers on the left side of the equation.

0.72 = 0.8 - 0.3x

Then move the variable to the left as well.

0.3x + 0.72 = 0.8

Move the constant to the right by subtracting.

0.3x = 0.8 - 0.72

Subtract the numbers

0.3x = 0.08

Divide both sides by 0.3.

And that should yield your answer.

Hope this helps. ^^
