Can any anyone help me with this problem please Solve : 2x - 1 = 7
ziro4ka [17]

Answer:

x = 4

Step-by-step explanation:

Solve for x :

2x - 1 = 7

-Add both sides by 1 :

2x - 1 + 1 = 7 + 1

2x = 8

-Take 2x and divide it on both side of the equation:

\frac{2x}{2} = \frac{8}{2}

x = 4

So, the value of x is 4.
