Question

Write an equation that requires at least three steps to solve and whose solution is x = 3.5.

Answer 1

We have to write an equation whose solution is x = 3.5, and it must require at least three steps to be solved.

The equation would be

`x+x+7=14`

To solve this equation, first, we sum like terms

`2x+7=14`

Second, we subtract 7 on each side

`\begin{gathered} 2x+7-7=14-7 \\ 2x=7 \end{gathered}`

Third, we divide the equation by 2

`\begin{gathered} (2x)/(2)=(7)/(2) \\ x=3.5 \end{gathered}`

Therefore, the equation you need is x + x + 7 = 14.
