Question

4.25 -2.5x = 14.75 I need help

Answer 1

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

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

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

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

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

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

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

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

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

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

$\text {Your Answer Would Be:}$

$\fbox {x=-4.2}$

$\text {Best of Luck!}$

Answer 2

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.

$\frac{-2.5x}{-2.5}= \frac{10.5}{-2.5}$

Now we simplify 10.5/-2.5.

$\frac{10.5}{-2.5}=-4.2$

$x=-4.2$

Hope this helps!
