The given equation is
[tex](x+7)=(2x-1)[/tex]
At first, we have to isolate x on one side and the numerical term on the other side, then
Add 1 to both sides
[tex]\begin{gathered} x+7+1=2x-1+1 \\ x+8=2x \end{gathered}[/tex]
Subtract x from both sides
[tex]\begin{gathered} x-x+8=2x-x \\ 8=x \end{gathered}[/tex]
The solution of the equation is x = 8
