Answer:

The solution to the given equation is


x=0

Step-by-step explanation:

Given the equation:


0.3x+1.8=0.4(x+5)-0.2

To solve this, we first remove the bracket on the right-hand side of the equation.


0.3x+1.8=0.4x+2-0.2

Next, we subtract 1.8 from both sides


\begin{gathered} 0.3x+1.8-1.8=0.4x+2-0.2-1.8 \\ \\ 0.3x=0.4x \end{gathered}

Next, subract 0.3x from both sides


\begin{gathered} 0.4x-0.3x=0.3x-0.3x \\ 0.1x=0 \end{gathered}

Divide both sides by 0.1


\begin{gathered} (0.1x)/(0.1)=(0)/(0.1) \\ \\ x=0 \end{gathered}
