Hey there!☺


Answer:\boxed{x=-4.2}


Explanation:


4.25-2.5x=14.75

Let's start by simplifying both sides in the equation.


4.25+-2.5x=14.75\\-2.5x+4.25=14.75

Now we subtract 4.25 from both sides in the equation.


-2.5x+4.25-4.25=14.75-4.25\\-2.5x=10.5

Now in our third/final step, we will divide both sides by -2.5.


(-2.5x)/(-2.5)= (10.5)/(-2.5)

Now we simplify 10.5/-2.5.


(10.5)/(-2.5)=-4.2


x=-4.2

Hope this helps!

\text {Hey! Let's Solve this Equation!}


\text {\underline {The First Step is to do Keep Change Change (KCC)}}


\text {Keep: 4.25}\\\text {Change: - into +}\\\text {Change: 2.5x into -2.5x}


\text {\underline {The Next Step is to Flip the Equation}}


\text {Before: 4.25+-2.5x=14.75}\\\text {After: -2.5x+4.25=14.75}


\text {\underline {The Next Step is to Subtract 4.25}}


\text {-2.5x+4.25-4.25=14.75-4.25=10.5}\\\text {-2.5x=10.5}


\text {\underline {The Final Step is to Divide -2.5}}


\text {-2.5x/-2.5=10.5/-2.5}


\text {Remember that Dividing a Positive to a Negative will Equal a Negative.}


\text {Your Answer Would Be:}


\fbox {x=-4.2}


\text {Best of Luck!}
