Si no me equivoco esto es: 1)3x-1=4x-3....4x-3x=-3+1.....x=-2 2)x+4/5=x/5-7/10....x+4/5= 5x-7/10....5x-x=-7/10-4/5....4x=-3/2...x=-3/2:4=-3/8 ...x=-3/8 3) 1-x-2/15=x/12......-x+1-2/15=12x.....12x+x=1-2/15.....13x=13/15 ....x=13/15:13.....x=1/15 4) x+2/3=4x+8/5 ....4x-x=8/5-2/3......3x=14/15 ...x=14/15:3=14/45..x=14/45 5)3x/4+3/2=2x-1.....12x+3/2=2x-1.....12x-2x=3/2+1.....10x=5/2...x=5/2:10=1/4...x=1/4 6)5x+2-3x-1=3......5x-3x+2-1=3...2x+1=3...2x=3-1=2...x=2/2=1...x=1 7)2x/5+x-4/10=4/15....10x+x-4/10=4/15....11x=4/15+4/10=2/3...x=2/3:11=2/33....x=2/33 espero haberte ayudado
2)x+4/5=x/5-7/10....x+4/5= 5x-7/10....5x-x=-7/10-4/5....4x=-3/2...x=-3/2:4=-3/8 ...x=-3/8
3) 1-x-2/15=x/12......-x+1-2/15=12x.....12x+x=1-2/15.....13x=13/15 ....x=13/15:13.....x=1/15
4) x+2/3=4x+8/5 ....4x-x=8/5-2/3......3x=14/15 ...x=14/15:3=14/45..x=14/45
