How to calculate 3x-5 + 2x = 4x-3

How to calculate 3x-5 + 2x = 4x-3

transposition
3x+2x-4x=5-3
(3+2-4)x=2
x=2

(4x + 1) (4x-1) - (2x-5) (2x + 3) calculation

（4X+1)(4X-1)-(2X-5)(2X+3)
=16x^2-1-(4x^2-4x-15)
=16x^2-1-4x^2+4x+15
=16x^2-4x^2+4x+15-1
=12x^2+4x+14

(4x + 1) (- 4x-1) - (2x-3) (2x + 3) simple calculation

Complete sum of squares square difference
Original = - 16x & # 178; - 8x-1-4x & # 178; + 9
=-20x²-8x+8

A simple method is used to solve the equation: 1 / 2 [X-1 / 2 (x-1) + 1] = 2 / 3 (x-1) on line, etc

1 / 2 [X-1 / 2 (x-1) + 1] = 2 / 3 (x-1)
x-(x-1)/2+1=4(x-2)/3
6x-3(x-1)+6=8(x-2)
6x-3x+3+6-8x+16=0
-5x=-25
x=5
