[src]
7*(2*x - 3) + 19 = 4*(x - 8)
$$7 \left(2 x - 3\right) + 19 = 4 \left(x - 8\right)$$
Detail solution
Given the linear equation:
Expand brackets in the left part
Expand brackets in the right part
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$14 x = 4 x - 30$$
Move the summands with the unknown x
from the right part to the left part:
$$10 x = -30$$
Divide both parts of the equation by 10
We get the answer: x = -3
7*(2*x-3)+19 = 4*(x-8)
Expand brackets in the left part
7*2*x-7*3+19 = 4*(x-8)
Expand brackets in the right part
7*2*x-7*3+19 = 4*x-4*8
Looking for similar summands in the left part:
-2 + 14*x = 4*x-4*8
Move free summands (without x)
from left part to right part, we given:
$$14 x = 4 x - 30$$
Move the summands with the unknown x
from the right part to the left part:
$$10 x = -30$$
Divide both parts of the equation by 10
x = -30 / (10)
We get the answer: x = -3
