Question

What is the solution to 4x-8=12 please explain

Answer 1

To solve an equation we need to isolate the unkown variable on the left side. To do that we will have to switch terms from one side to another of the equality, this is done by inverting its operations. If the term is adding it'll go to the other side by subtracting and if it is multiplying it will go to the other side by dividing, the oposite is also true.

With this in mind lets solve the expression.

`\begin{gathered} 4x\text{ - 8 = 12} \\ 4x\text{ = 12 + 8} \end{gathered}`
`\begin{gathered} 4x\text{ = 20} \\ x\text{ = }(20)/(4) \end{gathered}`
`x\text{ = 5}`

The value of "x" in this expression is 5.
