Given the equation 8x−6=3x+5 We raise the equation sides to 2-th degree 8x−6=3x+5 Move free summands (without x) from left part to right part, we given: 8x=3x+11 Move the summands with the unknown x from the right part to the left part: 5x=11 Divide both parts of the equation by 5
x = 11 / (5)
We get the answer: x = 11/5 check: x1=511 −3x1+5+8x1−6=0 = −5+53⋅11+−6+58⋅11=0 =
