4=7-6(5x-1) equation
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
4 = 7-6*(5*x-1)
Expand brackets in the right part
4 = 7-6*5*x+6*1
Looking for similar summands in the right part:
4 = 13 - 30*x
Move free summands (without x)
from left part to right part, we given:
$$0 = 9 - 30 x$$
Move the summands with the unknown x
from the right part to the left part:
$$30 x = 9$$
Divide both parts of the equation by 30
x = 9 / (30)
We get the answer: x = 3/10
