The solution
You have entered
[src]
5*x - 4*(6 - 7*x) - 3*(4*x + 3) = 2
$$- 3 \left(4 x + 3\right) + \left(5 x - 4 \left(6 - 7 x\right)\right) = 2$$
Detail solution
Given the linear equation:
Expand brackets in the left part
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$21 x = 35$$
Divide both parts of the equation by 21
We get the answer: x = 5/3
5*x-4*(6-7*x)-3*(4*x+3) = 2
Expand brackets in the left part
5*x-4*6+4*7*x-3*4*x-3*3 = 2
Looking for similar summands in the left part:
-33 + 21*x = 2
Move free summands (without x)
from left part to right part, we given:
$$21 x = 35$$
Divide both parts of the equation by 21
x = 35 / (21)
We get the answer: x = 5/3
