<h3><u>Given</u>:- </h3>

\red{➤}\:\sf AB = 5x

\red{➤}\:\sf BC = 3x+4

\\

<h3><u>To Find:-</u></h3>

\orange{☛}\:\sf Value  \:of  \:x

\\

<h3><u>Solution</u>:-</h3>

Since B is midpoint of AC, therefore -

\\\quad\quad\quad\quad\sf AB = BC

\begin{gathered}\\\quad\longrightarrow\quad \sf 5x = 3x+4\quad\quad ( Putting \:Value) \\\end{gathered}

\begin{gathered}\\\quad\longrightarrow\quad\sf 5x-3x =4 \\\end{gathered}

\begin{gathered}\\\quad\longrightarrow\quad\sf 2x =4 \\\end{gathered}

\begin{gathered}\\\quad\longrightarrow\quad\sf x =\frac{4}{2}\\\end{gathered}

\begin{gathered}\\\quad\longrightarrow\quad\boxed{\sf {x=2 }}\\\end{gathered}

B is the midpoint which means both sides are equal to each other:

5x = 3x + 4

Subtract 3x from both sides

2x = 4

Divide both sides by 2

X = 2

What would be the equation for #23???
Rufina [12.5K]
Hi there!

Let r be the number of matches that Rebecca's team won.

We know that Katheryn's team won 9 more matches than Rebecca's team, and we know that Katheryn's team won 52 matches.

Using this given information, we can create the following equation.

r+9=52

If you wish to solve this, we can subtract both sides by 9 to get the following value for r.

r=43

Have an awesome day! :)
