Me pueden ayudar con estas ecuaciones
1: 6x(x-3)+20=8-3x(5-2x)
2:z+45=-4-6z
3: 3(3v+4)=-4(2v-3)-8
4: -60-15z+30w-23z-3-12w+31+20z=
5: 3r-230x-100+12r+150x+90=
6: 6f+x+20-32f-13+2x=
7: -17-55f+102f-49f-25=
1: 6x(x-3)+20=8-3x(5-2x)
2:z+45=-4-6z
3: 3(3v+4)=-4(2v-3)-8
4: -60-15z+30w-23z-3-12w+31+20z=
5: 3r-230x-100+12r+150x+90=
6: 6f+x+20-32f-13+2x=
7: -17-55f+102f-49f-25=
20-8-5 =6x - 3x - 2x
7=x
2: z+45=-4-6z
45+4=6z-z
49=5x
49:5=x
9.8= x (Pone 9)
3:3(3v+4)=-4(2v-3)-8
3 3v-2v=4-8-4-3
3 1v=-19
1v=19
