\large\displaystyle\text{$\begin{gathered}\sf \frac{2x-20}{3}=2x  \end{gathered}$}

Multiply both sides of the equation by 3.

\large\displaystyle\text{$\begin{gathered}\sf 2x-20=6x \end{gathered}$}

Subtract 6x on both sides.

\large\displaystyle\text{$\begin{gathered}\sf 2x-20-6x=0 \end{gathered}$}

Combine 2x and −6x to get −4x.

\large\displaystyle\text{$\begin{gathered}\sf -4x-20=0 \end{gathered}$}

Add 20 to both sides. Any value plus zero results in its same value.

\large\displaystyle\text{$\begin{gathered}\sf -4x=20 \end{gathered}$}

Divide both sides by −4.

\large\displaystyle\text{$\begin{gathered}\sf x=\frac{20}{-4}  \end{gathered}$}

Divide 20 by −4 to get −5.

\large\displaystyle\text{$\begin{gathered}\sf x=-5 \ \ \to \ \ \ Answer \end{gathered}$}

Answer: Velveeta

Step-by-step explanation:

Unit rate is basically the price for a single slice. This being said you would divide 2.50 by 10 and you would get .25, then you would do 4.00 by 20 which would be .20. So the better deal would be Velveeta.

Anna71 [15]

<u><em>hi there user! Looks like your looking for help, so Mizuki came here to help you!</em></u>

the answer is:

<em>m is 2/3</em>

The whole work I did:

m + 4 ÷ 3 = 2

m + 4/3 = 2

m + 4/3 - 4/3 = 2 - 4/3

m = 6/3 - 4/3

m = 2/3

Anyways hope this helped! qwq
