Question

0.3x + 1.8= 0.4(x + 5) – 0.2

Answer 1

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}`
