20-7(5x-4)=6 equation
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
20-7*(5*x-4) = 6
Expand brackets in the left part
20-7*5*x+7*4 = 6
Looking for similar summands in the left part:
48 - 35*x = 6
Move free summands (without x)
from left part to right part, we given:
$$- 35 x = -42$$
Divide both parts of the equation by -35
x = -42 / (-35)
We get the answer: x = 6/5
