3x-1sobre2=5x+3sobre4=

Answer 1

2x +4 = 5x -5
4+5 = 5x -2x
9 = 3x
9/3 = x
3 = x
solucion x = 3

4x-1 = 6x -9
-1+9 = 6x -4x
8 = 2x
8/2 = x
4 = x
solucion x = 4

(4x +2)/2 = (7x +6)/4
4(4x +2) = 2(7x +6)
16x +8 = 14x +12
16x -14x  = 12-8
2x = 4
x = 4/2
x = 2
solucion x = 2

(7x +2)/3 = (3x+8)/2
2(7x +2) = 3(3x +8)
14x +4 = 9x +24
14x -9x = 24 -4
5x = 20
x = 20/5
x = 4
solucion x= 4

(3x -1)/2 = (5x +3)/4
4(3x -1) = 2(5x +3)
12x -4 = 10x +6
12x -10x = 6+4
2x = 10
x = 10/2
x = 5
solucion x = 5
