Question

How do you sold linear equations For 8th graders? For example 9x +2=4x+12 ?

Answer 1

Given:

The linear equation is,

`9x+2=4x+12`

To solve for x:

Step-by-step explanation:

Subtracting 4x on both sides, we get

`\begin{gathered} 9x+2-4x=4x+12-4x \\ 5x+2=12 \end{gathered}`

Subtracting 2 on both sides, we get

`\begin{gathered} 5x+2-2=12-2 \\ 5x=10 \end{gathered}`

Dividing 5 into both sides, we get

`\begin{gathered} (5x)/(5)=(10)/(5) \\ x=2 \end{gathered}`

Therefore, the value of x is 2.

Final answer:

The value of x is 2.
