2x = 5 + x x=5
7 = 4x - 1 7+1=4x 8/4=x x=2
x = 2x - 3 x - 2x = -3 -x = -3 se simplifican los signos x=3
3x =10 - x 3x - x= 10 2x=10 x= 10/2 x=5
3 = 2x - 5 3 + 5=2x 8/2=x X=2
x = 5x - 8 8=5x - x 8=4x X=2
x = 6 - x 2x=6 x=3
5 = 2x + 3 5-3=2x 2/2=x
x = 3x - 12 12=3x+x 12/4=x x=3
5x = 2 + x 5x-x=2 x=2/4 x=1/2
2 = 4x - 1 2+1=4x 3/4=x
x = 4x - 1 1=4x-x x=1/3
