The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Move free summands (without x)
from left part to right part, we given:
$$8 x = 7 x + 5$$
Move the summands with the unknown x
from the right part to the left part:
$$x = 5$$
We get the answer: x = 5
9-2*(-4*x+7) = 7*x
Expand brackets in the left part
92*4*x-2*7 = 7*x
Move free summands (without x)
from left part to right part, we given:
$$8 x = 7 x + 5$$
Move the summands with the unknown x
from the right part to the left part:
$$x = 5$$
We get the answer: x = 5
