4*x + 5 = -5*x - 7
4x+5=−5x−74 x + 5 = - 5 x - 7
Simplify
Detail solution
Given the linear equation:
4*x+5 = -5*x-7

Move free summands (without x)
from left part to right part, we given:
4x=−5x−124 x = - 5 x - 12
Move the summands with the unknown x
from the right part to the left part:
9x=−129 x = -12
Divide both parts of the equation by 9
x = -12 / (9)

We get the answer: x = -4/3
