The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Move free summands (without x)
from left part to right part, we given:
$$9 x = 175$$
Divide both parts of the equation by 9
We get the answer: x = 175/9
(x-6)*9 = 121
Expand brackets in the left part
x*9-6*9 = 121
Move free summands (without x)
from left part to right part, we given:
$$9 x = 175$$
Divide both parts of the equation by 9
x = 175 / (9)
We get the answer: x = 175/9
