x+(7-x)/3=4 equation
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
x+(7-x)/3 = 4
Expand brackets in the left part
x+7/3-x/3 = 4
Looking for similar summands in the left part:
7/3 + 2*x/3 = 4
Move free summands (without x)
from left part to right part, we given:
32x=35Divide both parts of the equation by 2/3
x = 5/3 / (2/3)
We get the answer: x = 5/2
