Question

What is the solution to 2x+10=28

Answer 1

Given the equation:

`2x+10=28`

to solve for x, first we have to move the constant 10 to the right side of the equation. When we do this, we have to change its sign to a negative sign:

`\begin{gathered} 2x+10=28 \\ \Rightarrow2x=28-10=18 \\ 2x=18 \end{gathered}`

Now we can divide both sides of the equation by 2 to get the following:

`\begin{gathered} (1)/(2)(2x=18)\Rightarrow(2)/(2)x=(18)/(2)=9 \\ \Rightarrow x=9 \end{gathered}`

therefore, x = 9
