Respuesta:
4x-7=5x-6/4 ...... x=2
4·2-7=5·2-6/4
8-7=10-6/4
1=10-6/4
1/1=10/1-6/4
../4=../4-../4
4/4=40/4-6/4
4/4=34/4
(x+2/3)=5x-4 ...... x=1
(1+2/3)=5·1-4
(1+2/3)=5-4
(1/1+2/3)=5/1-4/1
(../3+../3)=../3-../3
(3/3+2/3)=15/3-12/3
5/3=3/3
(2x-10/3x-20)=7/8...... x=12
(2·12-10/3·12-20)=7/8
(24-10/36-20)=7/8
(24/1-10/36-20/1)=7/8
(../72-../72-../72)=../72
(1728/72-20/72-1440/72)=63/72
(1728/72-1460/72)=63/72
268/72=63/72
espero te sirva saludos ^^
