0,4x-3,2=2,8 equation
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
(2/5)*x-(16/5) = (14/5)
Expand brackets in the left part
2/5x-16/5 = (14/5)
Expand brackets in the right part
2/5x-16/5 = 14/5
Move free summands (without x)
from left part to right part, we given:
$$\frac{2 x}{5} = 6$$
Divide both parts of the equation by 2/5
x = 6 / (2/5)
We get the answer: x = 15
