7,2:2,4=0,9х

To solve this equation, we need to simplify both sides by performing the necessary operations.

On the left side, we have 7,2:2, which means dividing 7.2 by 2. 7.2 divided by 2 is 3.6.

On the right side, we have 0,9 multiplied by x.

So, the simplified equation is: 3.6 = 0.9x

To solve for x, we need to isolate x on one side of the equation.

Divide both sides of the equation by 0.9: 3.6/0.9 = 0.9x/0.9

This simplifies to: 4 = x

Therefore, the solution to the equation is x = 4.
