X = 3

First u cross multiply

7x =3(2x +3)
Multiply parentheses by 3


7x = 6x =9
Move variable to the left

7x - 6x =9
Collect the terms

x = 9

Answer:

Our answer is
x=9

Explanation:

First we will rearrange so we have to divide by 7.


(x)/(3)= (2x+3)/(7)

Now we will cross multiply.

So...


x*7 \\3*2x+3

Our new equation will look like:


7x=6x+9

Now we have to isolate x.

So we have to subtract 6x from both sides.


7x-6=1x

and


6x-6x=0

Our new equation is:


1x=9

Now divide.

Our answer is
x=9

Hope this helped!
