4*(1 - 5*x) = 9 - 3*(6*x - 5)
$$4 \left(1 - 5 x\right) = 9 - 3 \left(6 x - 5\right)$$
Detail solution
Given the linear equation:
Expand brackets in the left part
Expand brackets in the right part
Looking for similar summands in the right part:
Move free summands (without x)
from left part to right part, we given:
$$- 20 x = 20 - 18 x$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-2\right) x = 20$$
Divide both parts of the equation by -2
We get the answer: x = -10
4*(1-5*x) = 9-3*(6*x-5)
Expand brackets in the left part
4*1-4*5*x = 9-3*(6*x-5)
Expand brackets in the right part
4*1-4*5*x = 9-3*6*x+3*5
Looking for similar summands in the right part:
4 - 20*x = 24 - 18*x
Move free summands (without x)
from left part to right part, we given:
$$- 20 x = 20 - 18 x$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-2\right) x = 20$$
Divide both parts of the equation by -2
x = 20 / (-2)
We get the answer: x = -10
