3(5-x)+13=4(3x-8) equation
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
3*(5-x)+13 = 4*(3*x-8)
Expand brackets in the left part
3*5-3*x+13 = 4*(3*x-8)
Expand brackets in the right part
3*5-3*x+13 = 4*3*x-4*8
Looking for similar summands in the left part:
28 - 3*x = 4*3*x-4*8
Move free summands (without x)
from left part to right part, we given:
−3x=12x−60Move the summands with the unknown x
from the right part to the left part:
(−15)x=−60Divide both parts of the equation by -15
x = -60 / (-15)
We get the answer: x = 4
