Answer:
[tex]x = 4[/tex]
Step-by-step explanation:
Solve for [tex]x[/tex] :
[tex]2x - 1 = 7[/tex]
-Add both sides by [tex]1[/tex] :
[tex]2x - 1 + 1 = 7 + 1[/tex]
[tex]2x = 8[/tex]
-Take [tex]2x[/tex] and divide it on both side of the equation:
[tex]\frac{2x}{2} = \frac{8}{2}[/tex]
[tex]x = 4[/tex]
So, the value of [tex]x[/tex] is [tex]4[/tex].
