Question

7.9% - 0.25 = 3.2 + x​

Answer 1

Answer:x=−3.371

Explanation:

Step 1: Simplify both sides of the equation.

7.9

100

−0.25=3.2+x

0.079+−0.25=3.2+x

(0.079+−0.25)=x+3.2(Combine Like Terms)

−0.171=x+3.2

−0.171=x+3.2

Step 2: Flip the equation.

x+3.2=−0.171

Step 3: Subtract 3.2 from both sides.

x+3.2−3.2=−0.171−3.2

x=−3.371

Answer 2

x = 3.391

Explanation:

first you calculate.

7.9% - 0.25 = 3.22 + x

divide the numbers

`(7.9)/(100)` - 0.25 = 3.22 + x

calculate again.

0.079 - 0.25 = 3.22 + x

move the terms

-0.171 = 3.22 + x

add the numbers

-x = 3.22 + 0.171

then change the signs

-x = 3.391

Final ans : x = -3.391

or some alternate answer's

x = -
`(3391)/(1000)` , x = -3
`(391)/(1000)`
