Identical expressions
- three (five -x)+ thirteen = four (3x- eight)
- 3(5 minus x) plus 13 equally 4(3x minus 8)
- three (five minus x) plus thirteen equally four (3x minus eight)
- 35-x+13=43x-8

Similar expressions
- 3(5+x)+13=4(3x-8)
- (4*x+1)*(4*x+2)=(7*x+4)*(3*x-8)
- 3(5-x)-13=4(3x-8)
- 3(5-x)+13=4(3x+8)

The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Expand brackets in the right part
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
Move the summands with the unknown x
from the right part to the left part:
Divide both parts of the equation by -15
We get the answer: x = 4
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:
Move the summands with the unknown x
from the right part to the left part:
Divide both parts of the equation by -15
x = -60 / (-15)
We get the answer: x = 4
