___ ____ _____ -\/ 5 *x = \/ 45 - \/ 125
$$- \sqrt{5} x = - \sqrt{125} + \sqrt{45}$$
Detail solution
Given the linear equation:
Expand brackets in the left part
Expand brackets in the right part
Divide both parts of the equation by -sqrt(5)
We get the answer: x = 2
-sqrt(5)*x = sqrt(45)-sqrt(125)
Expand brackets in the left part
-sqrt5x = sqrt(45)-sqrt(125)
Expand brackets in the right part
-sqrt5x = sqrt45-sqrt125
Divide both parts of the equation by -sqrt(5)
x = -2*sqrt(5) / (-sqrt(5))
We get the answer: x = 2
