Answer is 14x

Step by step

2x + 5 = 10 - 3x

Let’s start with 2x + 5 = 7 and you bring the x with you which is 7x

Now you do 7x = 10 - 3x , equal sign is plus am guessing and then 10 - 3x is 7x so

7x + 7x = 14x

Answer:

$\huge \boxed{ \boxed{z = 3}}$

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>

equation
PEMDAS

<h3>let's solve:</h3>

$\sf simplify \: substraction : \\ \frac{3}{ \frac{z - 2}{z} } = 3z$
$\sf simplify \: complex \: fractio n : \\ \frac{3z}{z - 2} = 3z$
$\sf cross \: multiplication : \\ 3z = 3z(z - 2)$
$\sf divide \: both \: sides \: by \: 3z : \\ \frac{3z}{3z} = \frac{3z(z - 2)}{3z} \\ 1 = z - 2$
$\sf add \: 2 \: to \: bot h \: sides : \\ z - 2 + 2 = 1 + 2 \\ \therefore \: z = 3$
