Answer:-1.5

Explanation:

first distribute 3

to get 6x + 3= 4x

Hello !

Answer:


\Large \boxed{\sf x=-(3)/(2)}

Explanation:

We're looking for the value of x that satisfies the following equation :


\sf 3 (2x+1) = 4x

We need to isolate x.

First, let's expand left side :


\sf 3* 2x+3*1=4x\\6x+3=4x

Now let's substract 4x from both sides :


\sf 6x+3-4x=4x-4x\\2x+3=0

Substract 3 from both sides :


\sf 2x+3-3=0-3\\2x=-3

Finally, let's divide both sides by 2 :


\sf (2x)/(2) =-(3)/(2) \\\boxed{\sf x=-(3)/(2)}

Have a nice day ;)
