7.9% - 0.25 = 3.2 + x​
seraphim [82]

Answer:

x = 3.391

Step-by-step explanation:

first you calculate.

7.9% - 0.25 = 3.22 + x

divide the numbers

\frac{7.9}{100} - 0.25 = 3.22 + x

calculate again.

0.079 - 0.25 = 3.22 + x

move the terms

<u>-0.171</u> = <u>3.22 + x</u>

add the numbers

<u>-x = 3.22 + 0.171</u>

then change the signs

<u>-x = 3.391</u>

Final ans : <u>x = -3.391</u>

or some alternate answer's

x = -\frac{3391}{1000} , x = -3\frac{391}{1000}
