11-5(4×-3)=4 equation

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

You have entered [src]

11 - 5*(4*x - 3) = 4

11 - 5 \left(4 x - 3\right) = 4

Simplify

Detail solution

Given the linear equation:

11-5*(4*x-3) = 4

Expand brackets in the left part

11-5*4*x+5*3 = 4

Looking for similar summands in the left part:

26 - 20*x = 4

Move free summands (without x)
from left part to right part, we given:

- 20 x = -22

Divide both parts of the equation by -20

x = -22 / (-20)

We get the answer: x = 11/10
