Question

My name is Nika and I need help in math I’m 73 and done with school but still don’t under algebra

Answer 1

The given equation is

`2x-3=9`

To solve this equation we have to isolate x on one side and put the numbers on the other side

To do that we will add 3 to each side to move 3 from the left side to the right side

`2x-3+3=9+3`

Simplify it

`\begin{gathered} 2x+0=12 \\ 2x=12 \end{gathered}`

Now we need to move 2 from the left side to the right side, then

Divide both sides by 2

`\begin{gathered} (2x)/(2)=(12)/(2) \\ x=6 \end{gathered}`

Then the solution of the equation is

x = 6
