Question

0.3x + 1.8= 0.4(x + 5) – 0.2

Answer 1

Answer:

The solution to the given equation is

$x=0$

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

$\begin{gathered} \frac{0.1x}{0.1}=\frac{0}{0.1} \\ \\ x=0 \end{gathered}$
