0.4 (2x+0.3) = 1/3 (6x-7.2)

Answer: The solution is x = 2.1

Step-by-step explanation:

The equation is:

0.4 (2x+0.3) = 1/3 (6x-7.2)

We need to isolate x and find the value of it:

First, we multiply by 3 in both sides:

3 * (0.4 (2x + 0.3)) = (6x - 7.2)

Now, we distribute the first multiplication:

1.2*2*x + 1.2*0.3 = 6x - 7.2

now, we send al the therms with x to the same side, and the others to the other side:

2.4*x - 6*x = - 7.2 - 1.2*0.3

- (3.6) * x = - 7.56

Now, we divide both sides by - 3.6

x = - 7.56/-3.6 = 2.1
