0,12x-20=4 equation
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
(3/25)*x-20 = 4
Expand brackets in the left part
3/25x-20 = 4
Move free summands (without x)
from left part to right part, we given:
$$\frac{3 x}{25} = 24$$
Divide both parts of the equation by 3/25
x = 24 / (3/25)
We get the answer: x = 200
