2(x-4)=1 equation

The teacher will be very surprised to see your correct solution 😉

You have entered [src]

2*(x - 4) = 1

$$2 \left(x - 4\right) = 1$$

Simplify

Detail solution

Given the linear equation:

2*(x-4) = 1

Expand brackets in the left part

2*x-2*4 = 1

Move free summands (without x)
from left part to right part, we given:
$$2 x = 9$$
Divide both parts of the equation by 2

x = 9 / (2)

We get the answer: x = 9/2
